There are all kinds of reasons why games got delayed, from a lack of resources on the development side to corporate politics on the publisher side. Nobody wants to play a bad or unfinished game, but we still can't help but feel a tinge of disappointment when a game we are looking forward to gets pushed beyond its original release date even if we know it is typically for the best. That said, when game delays start stretching into years past when they were originally supposed to come out, there is often more going on behind the scenes than just a need for additional polish-- and it's usually not good news.

As the title of this list indicates, however, things aren't going to be all doom and gloom here. We've dug up an equal number of examples of games that got hung up in development for a protracted period and ended up being worth the wait as well as games that were massive disappointments. It should also be noted that not all of our "not worth the wait" entries are necessarily bad games, just that they didn't end up living up to the expectations that their years of hype set us up for.

Not Worth The Wait: Spore

Will Wright's place in the pantheon of legendary video game designers is firmly cemented, as he is the brains behind SimCity and The Sims. In fact, it's only someone with Wright's stature that could have his as-of-yet final video game release be something as monumentally disappointment as Spore and still not have anyone question his legacy.

Spore is nothing if not ambitious, and it's certainly fun to mess around with... for a little while. But it quickly becomes apparent that it never quite achieved what it set out to achieve from a technical or artistic standpoint, and what was left behind to make up for that fact is gameplay that is extremely simplistic and repetitive.

Worth The Wait: Eternal Darkness: Sanity's Requiem

Sometimes, a game is in development for so long that the original platform it was in development for is retired before the game is finished. Such was the case with Eternal Darkness, which began life as a Nintendo 64 game before developer Silicon Knights realized it wouldn't be done soon enough and they instead decided it should be a launch game for the GameCube... though that also proved too ambitious of a deadline.

When ED finally hit stores in June 2002, it wasn't a huge seller but received high acclaim from critics and gamers alike, remaining one of the most-requested games from that era for the HD remaster treatment.

Not Worth The Wait: Daikatana

What is it about FPSs from industry legends that seem to have a tendency to go so badly? After being one of the key creative forces behind such iconic titles as Wolfenstein 3D, Doom, and Quake, John Romero left id Software in the mid-'90s to form his own company (Ion Storm) and work on something with which he finally had full creative control.

First announced in 1997, John Romero's Daikatana fell victim to a legendarily troubled development cycle and abysmal reviews post-launch. The game remains a cautionary tale for believing your own hype, letting ego get the best of you, and failing to acknowledge the other people who helped get you to where you are.

Worth The Wait: Alan Wake

Even though Finnish video game developer Remedy Entertainment has been around for 23 years, they've only managed to release seven unique video game titles in that time. Much of that has to do with how long the company took to make its two most well-known releases: Max Payne and Alan Wake, with those games alone taking a combined 12 years to create.

Alan Wake was first announced in 2005 for "next generation consoles," and wouldn't find its way to Xbox 360 until 2010 (with a PC version following a whole two years later). But it was released to rave reviews and numerous awards, including Time magazine calling it the best game of the year.

Not Worth The Wait: Perfect Dark Zero

Those who were around for the split between Nintendo and its longtime developer partner Rare  what a huge shock it was. Even more surprising was that it was Microsoft who snatched up the UK-based developer, enlisting the team to hopefully do for the Xbox what they had done for the SNES and N64.

Having long-awaited sequel Perfect Dark Zero as an Xbox 360 launch game was extremely exciting, and expectations were sky high after years of delays that pushed the game from one console to the next. Sadly, PDZ ended up being one of the biggest disappointments of the 360's launch lineup, and the franchise has never recovered.

Worth The Wait: Fallout 3

Bethesda is taking a lot of flak these days, as is the Fallout series, and rightfully so. But people wouldn't be so hard on the company or disappointed in the current state of Fallout if both hadn't set such a high bar with the release of Fallout 3.

Van Buren, the code-name given to what was originally intended to be the third Fallout game, was shut down in 2003 after about five years of development. Shortly after, Bethesda acquired the rights to the series and started their Fallout 3 from scratch shortly after. While some old-school Fallout/Wasteland fans felt Fallout 3 strayed perhaps too far from its lineage, the game is otherwise considered a modern classic.

Not Worth The Wait: Too Human

With a game like Eternal Darkness under its belt, not to mention the classic RPG Blood Omen and the well-received GameCube remake of Metal Gear Solid, Silicon Knights should be a company that is ed fondly by gamers. But it wasn't just the tendency of founder Denis Dyack to go to war with anyone who criticized his games that hurt the once-beloved company's reputation— it was major disappointments like X-Men: Destiny and Too Human.

Starting development as a PS1 game, Too Human finally hit the Xbox 360 in 2008 and still felt clunky and unfinished. Dyack vehemently defended his game in interviews and on message boards, but that ultimately just made things worse.

Worth The Wait: Resident Evil 4

It has been said that as many as four versions of Resident Evil 4 were thrown out before work started on the one that actually got released. After six years of false starts, RE4 finally hit the GameCube in 2004 and was almost unanimously hailed a masterpiece.

Considered one of the greatest and most influential video games ever made, RE4 completely changed third-person action games in particular, setting the mechanical and tonal template for future classics like Gears of War, Batman: Arkham Asylum, and The Last of Us. RE4 has since been ported to just about every platform that has been released in the last 15 years, and it never stops feeling fresh or exciting.

Not Worth The Wait: Galleon

how we alluded to Tomb Raider's creator leaving the franchise behind to make an inferior copycat game? Well here is that game, the pirate adventure game Galleon by Tomb Raider and Lara Croft designer Toby Gard.

After growing justifiably frustrated with the growing creative interference by publisher Eidos— especially in the way they were amping up Lara's physical assets to market the series— Gard quit developer Core Design and left Lara behind in order to create a game he'd have full creative control over. After years of delays, Galleon for Xbox proved an instantly-forgotten dud, and Gard would eventually return to Tomb Raider to help guide the acclaimed 2006 reboot.

Worth The Wait: Owlboy

Following in the tradition of long-in-development labors of love created by small teams that throw back to the 8 and 16-bit gaming eras that also includes games like Fez, Cave Story, and Retro City Rampage, Owlboy's total development time stretched for nearly a decade and had to deal with astronomically high expectations upon its eventual release. Only Owlboy might very well be the best of that bunch.

Inspired by Super Mario Bros. 3— specifically, the mechanics of the Tanooki suit— Owlboy feels like a love letter to mid-'90s 2D platformers that will delight both gamers who grew up during that era and those that are just looking for an expertly-crafted Metroidvania-style adventure.
