Best: Take-Two

Worst: Square-Enix

i'll say no one = )

I don't have one that did the worst, because i mean they all are doing pretty good, but i do know the one with the biggest regrets, and that's the publisher that did Duke Nukem... all of them that were involved... ever....
But the best would have to be Nintendo, they kicking A and taken names right now

Best? Take-Two

Favorite? Atlus (They gave me Demon's Souls when SONY wouldn't!)

Worst? I've been waiting for VSXIII before the PS3 released...

Best: Nintendo, but Sony has made some amazing games too, and the best is yet to come (TLG)

Worst: Hard to tell, possibly an unknown one, but IMO, EA sucked in my favorite console, so this goes to them.

Also, what's with all the Square Enix hate? Just because FF13 was linear and they make waaaay too many games at once?

Nintendo hands down! Sony were very impressive.

Best is easily Sony, just the sheer amount of quality they've released should put them up and above every other publisher.

The best publisher/developer without a stake in a console they own would probably be a tie between SEGA, Bethesda and EA.

The worst would be Nintendo.Screw you Nintendo. Disney Interactive also sucks.

Best new comer is Warner Bros.

Best = Nintendo
Worst = THQ

Most improved = Level 5
Biggest deterioration = Square-Enix

Think it's fair to say activision did rather good lol
