COD (I see no fun in this)
Super Mario Galaxy (could have been OK, it sucks because of the wiimote).
Super Mario 64 (just because it's everyone's No1, I think it stinks graphically (don't tell me it is the first 3D graphic adventure.... boooh, diddy kong on the same machine DOES look good), no action, too much humping trees, too slow, boooring).
Super Mario Kart series (could be OK, but the computer is really a pain in the ass with the assignment of goodies, I want lightning and red turtles in the first position too! Other carts behind outside view go faster than all others looking at the speed of the dots of the map. Peach is always helped. Being stuck behind obstacles really stinks).
Super Metroid (boooring, slow, too large, did I mention SLOOOOOWWWW).
Yoshi's Island (unbearable because of the abducted baby sound!)
Angry Birds (another sound-problem for my ears).
Oh, BTW sonic haters in this topic: I love Sonic. The Game Gear version rules. Great sprites, decent gameplay, not the over-the-top levels of the Genesis and the best music on any 8-bit platform.
