I played the first one a little, but I have played the second one quite a bit since release, and come back to it still and can get good quality time out of it.  Anyone here play this?  It is more of an action/shooter with rpg elements glued on, but they are glued on well.

Played it a ton with my GF.
I'd really consider it the best co-op game (within that genre) out there.

We stopped playing as soon as we hit Veteran, though, as my GF couldn't quite keep up at that level - while I got somewhat bored of anything below it.
Plus, we had already played all the classes, found our favourites, knew all the maps, etc.

Playing with random people was a nightmare, though, as people would just run off or do other stupid crap to get everyone killed.
One of the few instances where bots are genuinely more useful than other people.

It's a shame that Fat Shark is so slow in producing more content.
Though I think we'll come back once Kerillian, Victor & Sienna get new classes - if that ever happens, that is.
Hopefully at that time, there'd be some new maps as well so it would be enough content to get back into the game.
