Sony. Even before I knew about who sony was i played their games without even realising it. I only found out about developers and stuff this generation.
PS1 - Crash, Spyro, Ape Escape, Twisted Metal, Gran Tursimo, wipeout, syphon Filter, A bugs life. You get the picture. I loved all these games without even knowing where they come from.
PS2 - Gran Tursimo, Twisted Metal, God of War, Singstar, Jak, Wipeout.
Fast forward to today and this still has not changed. Sony still consistently make games I love above all other publishers.
PS1 they were the best publisher.
PS2 - Had 8 really amazing games i would not have passed up. Also my favourtie, Jak n Daxter
PS3 - they were the best publisher
I dont know about worst because I dont really pay attention to crappy publishers. If you want me to mention high profile pulishes I do not rate, than
activision (I aint even sure i have purchased a game from them with my own money this gen)
Microsoft (Never liked their games, though I did love Fable before they ruined it)
Square enix (Just for how far they have falling)
I am sure their are publishers around who are far worse. I mean what geniuses thought it were a good idea to sell Angry Birds for 30 quid on the PSN store?
Nobody's perfect. I aint nobody!!!
Killzone 2. its not a fps. it a FIRST PERSON WAR SIMULATOR!!!! ..The true PLAYSTATION 3 launch date and market dominations is SEP 1st
