Just a single post has mentioned Arkane so far. So I need to write it in capital letters: ARKANE!
Not a single post mentioning Ninja Theory?! NINJA THEORY! :P
Also: CD Project Red, Nintendo, Monolith Soft, From Software, Larian Studios, Ninja Theory, Remedy, Capcom, Sony Santa Monica, Platinum Games. Lots of RPG powerhouses. I like a lot more studios but these are the one's I like multiple franchises from. IO Interactive is also quickly becoming a new fave of mine. Expecting good things from Obsidian and inXile in the future, too. I also enjoy the stealthy gameplay of Eidos, although they have been a bit hit and miss with their games this gen.
