It was announced today that Mass Effect 2 is set to appear on store shelves for the PS3 in January 2011. Along with the full version of the game, there's also going to be "hours of bonus content" included.

I've heard good things about this game, so I'm definitely interested in seeing it appear on a game console that I have, though I wonder just how this will work considering that I don't have/never played the first one, and there's no news on a port of that game heading to the PS3... Some comments I've read on different sites say it doesn't matter, and others a dead set on "if you haven't played the first one, then you won't have a feel for the mythology and characters!"

Anyone have any thoughts on this?
