Bioshock
Nice storytelling and interesting setting and plot, marred by extremely boring gun action and minigames, overall monotony and a scarce sense of accomplishment due to the way vita-chambers work.

GTA IV: It felt like a downgrade compared to the previous ones. Subpar HD graphics are not enough to impress me.

Dead Rising: I don't know what's with this game but I've never really impressed. Yes, there's a lot of zombies and a lot of possibilities, but this game gets boring after 5 minutes. It's always the same.

Metal Gear Solid 2: Sons of Liberty. Heard so many good things leading up to this game that I had to buy it the day it was released.

Took it home, watched the opening video, played about 1 hour, and took it back; have never been interested in a Metal Gear game since. For those who get it, I'm sure they are incredible...they just aren't for me.

The GTA series, i don't even consider it a masterpiece, well I kinda do, a masterpiece of major crap.

This thread is much more tame than I expected it to be.

Anyway..

FFVII
Halo 2
EDIT: Final Fantasy Tactics Advance
Kingdom Hearts: Chain of Memories
Jak I
The World Ends With You
Oblivion

and some that I thought were good but not masterpieces
Crash I
Gears I
Chrono Trigger

Any Half-Life
Portal
Halo 2 & 3

Bioshock.

Sound seemed weird to me. I couldn't tell where a sound (i.e. bad guy) was coming from.

And then once I'd spotted them the shooting seemed ridiculously inaccurate. Even if they stood still I doubt I would've been able to hit them.

Probably my fault for being rubbish, but I couldn't stand the game. Got it in a sale thinking I'd get a decent return on it but I think I got £2 for it on trade in. That made me double hate it!!!!

FFVII

that's one I hate. there are a lot that I don't like that much, or don't think they are "masterpiece", but FFVII I don't like at all!
