Here's some specific ones for Nintendo, Microsoft & The PlayStation Company
The Big N
- too many under-supported and under-utilized accessory's (wii zapper, wii wheel, wii speak, even balance board to an extent with 3rd partys)
- Animal Crossing: City Folks - if you're going to make a AC game make an effort Ninty
- Wii Music
- E3 2008
Microsoft
- ludicrously unreliable hardware from launch till 2007/8 (don't know which year they sorted it out somewhat, I hear its apparently pretty reliable now)
- no built in wi-fi
- no full BC for xbox
- making their console look nice instead of a fat brick thus ruining comedy for a generation
Sony
- a launch price so high you had to take out a 2nd mortgage
- no PS2 BC
- making us wait for dualshock 3 and instead giving us the average sixaxis for what seemed like an eternity that could have been better spent waiting to destroy Optimus Prime (+3 for anyone who gets that reference)
- so bad its bad marketing (seems to be better recently)
