Wii play. It was only 10 bucks, but I do not think I have even played 10 bucks worth of it.

Easily Bioshock. It's not that it was a bad game, but the reviews made me think it was the second coming of Jesus here to save gaming. I discovered it was just a dumbed down version of System Shock 2 with awesome water effects and ambiance.

Other than that, Final Fantasy VII. I bought a PSone for that game and hated it. However, it's hard for me to completely hate it because if it hadn't convinced me to buy a PSone I wouldn't have gotten to play Final Fantasy IX, which I absolutely loved. Not to mention all the other awesome PSone games (Crash Team Racing ftw).

Chrono Cross.... ugh.

An Xbox. That's the first game console I have ever regretted buying. That includes the Saturn and Dreamcast. I bought it for Halo 2 online but I couldn't stand the immature kids on Live and stopped playing. The Xbox just rusted after that. Fable was really the only thing that made it close to worth it for me.

Final Fantasy XII. See: Chrono Cross

Ratchet and Clank: Size Matters. It's like they took everything I loved about the PS2 games and royally f***ed it up.

Mario 64 DS. It just had none of the feeling of wonder that made SM64 great.

I could keep going for a really long time.

I never have regretted a game buy. Never, seriously. I try to buy the stuff I know is good and that I will like.

Red Steel. Oh god, it was awful.

Regrets, I've had a few, but than again too few to mention.... Ah, what the heck here I go.

PS3 regrets: Motorstorm, Resistance, Transformers, That RPG I can't even remeber the name it was so bad, Lair.

Wii regrets: Mario Party (great game, but that is all my friends ever want to play anymore), One Slot Wii-mote Charger (shoulda bout the double), Super Paper Mario (I wanted to like it soooooo bad)

Xbox 360: I regretted buying the Xbox 360, now I regret selling it.

DS: Spending 48 hours playing EBA.... I want my 2 days back. (Great game though)

PC: WoW... see EBA.

I regret buying Halo 2 PC back in May. What a waste of $50...(I thought it would be as good as Halo 1 PC)

This may be a surprise to some since I played the game and had pretty high opinions of it, but with Bioshock looking back at the game there wasn't anything that really makes me want to play it again. With games like HL2 there is the ZPFM and the DEZPFM, with Smash its always about the back and forth competition and pretty much all of the really great games have some reason to go back and play it again. But about 2 weeks ago I sat down to play the game again and after like 20min I was playing TF2 =P

Its not b/c I felt like playing TF2, it was just that it didn't feel like I was doing anything new or exciting since I had already played through that part before.

Bioshock is a good game, no doubt, but I think what it excels at is the most is a great first experience and it lacks in replay value considerably imo. I don't think they should have tacked on multiplayer or anything, and honestly I don't know that there was anything they could have really done to make the game more interesting to replay.

Same here, I played RE0 after playing RE4 and hated the controls so much that it's the only Resident Evil game on console (that I've played) that I never bothered to finish.

My disappointments, Part 2:

FEAR.  This game got amazing reviews but both the horror and shooter aspects were lackluster compared to others in the genre.  After Half-life 2 the game felt like a joke.  

Metroid Prime Hunters... oh man this game probably tops my list (both lists).  It was a great handheld shooter, but it was not a Metroid game.  At all.  It had no adventure elements, was short, linear, and full of combat.  It felt more like Halo.  Nothing against Halo, but I don't want my Metroid made into Halo.

Innocent Life.  Worst Harvest Moon I have played since Harvest Moon: A Wonderful Life on GC.  Thank god Rune Factory was good.

KOTOR 2.  It just wasn't as great as KOTOR.  Too much copy-pasting.  

Okay I need to stop listing things that have disappointed me.  It's making me depressed. 

Ah i forgot FF7.  Probably because i gave it away.
