Nintendo. For screwing with Sony on the SNES-CD project. Luckily it was the catalayst for the original Playstation console, a console so perfect for it's environment and timing that only the Atari VCS was comparable in genius.
NES - for all the overpriced crappy Mario games and terrible rock hard square joypads.
Gameboy - For every putrid Pokemon game, cancer to the gaming world propping up themselves whilst Sony tore them a new one in the home console market.
SNES - For putting such a stupidly slow CPU in a machine AFTER the Genesis/Megadrive. Also for all the babying of their userbase by removing all the blood from MK. Oh and putrid Mario games.
Wii - Pathetic PS2-o-clock graphics, and some extremely woolly controllers, all for a rip off price above that of the 360. Oh and yes the controllers are inaccurate toys because now we have Wii+ controllers wooppeeee lol
DS - Abolutely pathetic technical spec at launch, couldn't even play video files on the go for the price. Total joke except for Korg's DS10 cartridge....all those other silly brain training games can lick my left one.
Think that covers it, oh yes except for the fact they screwed you all over by getting exclusive console rights to Tetris due to some Russian fool not following correct procedure (hope that idiot is in a goulash for that sin). Nintendo are as much scum as Microsoft, I hope there is some massive financial catastrophe where they both simultaneously sink without a trace from the world...sooner the better
