sam_higton: Recently, me and a flat mate have been playing a lot of dungeon siege cooperatively. We've been having a wail of a time, but we're getting pretty close to completion and looking for something else.
So, does anybody have a suggestion for a good RPG (preferably action based), along the lines of dungeon siege? So far we've tried dungeon siege 2 and space siege, but weren't impressed. Diablo 2 was great in it's day, but I'd prefer something with a little better graphics.
Sacred Gold is released on GOG on Tuesday, which looks rather tempting, but I've no idea whether there's co-op play.
So, fellow GOG goers, what would you recommend?
Sam

DukeNico: Hey, I also played Dungeon Siege in LAN someday it was damn fun :D That was a good choice mate. I could recommend youBaldur's Gate Dark Alliance if you have a PS2. I played it at my cousin's place with him in co-op and it was pretty cool too, really action based too.
... Diablo 2? :D
That's all I can do for you, I don't really play RPGs which can be co-op'd, but if Titan Quest has a co-op mode I'd recommend it for you (even if I haven't tried it, I've heard it is a great game!).

CymTyr: Next year or the year following Diablo 3 will be upon us, but that's a ways off. Other than that, there's slim pickings unless you go with some older games. Sacred Gold would be a good choice, but I'm not sure how GOG will handle the MP aspect of it, since in the original you needed a cd key to play MP.
You could always play NWN 2 on a persistent world with your friend if you want to try that, though there aren't many PW's for NWN 2. It's an option though, and I think if nothing else you can play the campaign with your friend either on a public server or you should be able to host a game.

sam_higton: Titan Quest is something I should also look into; I've heard mixed opinions about it, but it does look rather interesting.

McDondo: I've been playing it with a friend, it's kinda fun in the way Diablo 2 was, minus the "story" part.
I think action RPG's are played only to get the cool gear and kill, like, 2 bajillion bugs with it. So in that aspect, Titan quest is fun to play with a buddy. Plus you can select 2 "classes" that make some interesting character combinations.
it's like Dungeon Siege, with better looking graphics, minus the mule :D

Granite: Titan Quest does have a story, and even a fairly decent one. The problem is that much like Diablo 2 or Dungeon Siege, you're briefly told what to do, then you spend the next two hours slogging through monsters to get to the next point. Narrative is rather hard to maintain under those circumstances.
However, it has an excellent character customisation scheme. You can choose any two power sets, so you can be a swordsman with elemental powers, a necromancer who summons nature based pets, an archer with defensive and protective powers, and any other combination you fancy. Add in friends with yet more combinations, and you've got a staggering array of abilities on call.
It's a really under-rated game, in my opinion. It may not be revolutionary, but it's a solid evolution of the Diablo play style. If it had a diffferent plot and been called Diablo 3, I'm sure that people would have heralded it as the greatest RPG ever. As it is, I have a sneaking suspicion it's going to be more revolutionary than Diablo 3, but we'll see how Blizzard does.
Oh, as a complete diversion, I know if t doesn't match what you're describing, but System Shock 2 has a co-op mode, and it is truly awesome. :)

sam_higton: How could I have overlooked this game for so long?!
Thanks for the suggestions everybody
