^ Beware of flamebait

It's why I own a rubber jacket.

Well, if I never played a game, then I cannot say I didn't like it even though it never caught my interest enough to buy or rent.

Out of the ones I played that I didn't like:
GTA: San Andreas
Zelda II - mostly because I found it too hard.
Super Paper Mario - because there was so much to read, but the gameplay was good though.
Sonic I
Alex Kid I
Jillian Michaels Fitness (don't know if most people liked it, but it does have good sales)
PES08 - is good but I suck at it
Super Mario Strikers - like the easy matches, hate the online 'cause I suck at it

Little Big Planet
Sonic The Hedgehog 3

Resident Evil 5, felt just like RE4 but in africa with stupid game play ideas(i have to stand still to shoot...), a terrible inventory system, and enemies that stare at me for at least 5 seconds before doing anything.  

Halo
Splinter Cell (really really dull)
San Andreas (admitedly only played about an hour of it)

Lylat Wars (eugk)
Sin and Punishment
Anything which stars Donkey Kong

Excite Truck seems to be really loved... I think it is a good game, but not anything uber special.

Halo
Grand Theft Auto
Racing Genre (with the exception of Mario Kart and Diddy Kong Racing)

Halo (all)
Left for dead
Infamous
GTA IV
Gears of war (all)
Bioshock
Rock Band & Guitar Hero (all)
Call of Duty: Modern Warfare
Mass effect (all)
Fuel
Fable 2
Splinter cell (all)

lAny music game

Halo 3 (X360)
Knights Of The Old Republic (Xbox)
Super Smash Bros (all),
Warhawk (PS3)

That's all I can think of right now.
