I think EA sports and Electroinc Arts are not very good, can´t really think of any "killer" games they´ve had recently.
Anecdote: I went jogging 30 minutes ago and I ran by their Norwegian HQ, didn´t know it was there. Wonder what they actually do there?
Konami makes good games, Capcom has had a few great games, Nintendo also has made some quality stuff. Most of my knowledge of game makers come from my SNES days, don`t know anything too recent.
