Atlus. They only publish top quality games, unlike pretty much every other 3rd party publishes.

Namco...


...
... hahhaha, of course not. Anyone from Europe that likes Namco is nuts.

I like Ubisoft, simply because they bring a lot of games (that aren't even their) to Europe.

I'll take Ubisoft, but now that EA is going to start publishing Bioware and is already publishing Valve, that will likely change soon.

Activision for CoD and other games.

Square-Enix. Gaming wouldn't be that good for me if they weren't around.

A lot of my games are EA so EA for me. SEGA has a few, and huge points for them and CA's Total War. Ubisoft if it were last gen. This gen I'm really REALLY dissapointed =( I've returned 2 of their games (Double Agent and Assassin's Creed), HATE Far Cry 2 (but I bought it near full price and I won't get a lot back >.

Although this is a pretty old thread, my vote goes probably to Capcom.

They've brought us great games this gen: Street Fighter 4, Resident Evil 5, RE Umbrella Chronicles and other RE games (although lots of ports), Lost Planet, Dead Rising, Devil May Cry 4, Monster Hunter games

EA and Ubisoft are also doing their job very well.

Capcom takes the prize, then EA. Activision Blizzard would be #1 (or close to it), but Starcraft II hasn't been released yet.

1. capcom
2. konami
3. square

activision and EA shouldnt even be on this list for best publisher IMO
