Bethesda. Their games are sloppy, and they only seem to rely on how big they can make a game world.

Square Enix. They take WAAAAAAAAAAY too long to finish games.

Bioware. Mass Effect 3

EA goes without saying... and maybe Square Enix, but I still kinda enjoy their games.

The only one I can think of is some company called codemasters. There far from codemasters and there non racing games suck.

Naughty Dog, i'm a fan of Jak and Uncharted series, I also loved Crash bandicoot.
Insomniac, because of Ratchet and Clank and Spyro the Dragon

and at some point Ubisoft, they have a few games that I really like

No,this post is about your least favorite game developers. the ones,you don't care for.

I didn't read the entire title sorry lol, in that case

FUCK ACTIVISION
FUCK EA
FUCK EPIC GAMES
and fuck Ubisoft somehow

Activision for making the same repetitive crap over and over again (cough Call of Duty cough)

Edit: Activision is the publisher so Infinity Ward, treyarch and slegdehammer

You watch AVGN too?

yep
