EA - pretty much all of their games stink. They've made so much generic and cheaply developed crap that it's disgusting.
Blizzard - I hate that they are so overrated. I actually only liked the first Warcraft. I dont like the style of any of their other games.
Square Enix - people regard them as some kind of Gods for some mysterious reason. In my opinion JRPG is the worst genre in gaming.
