Can anybody recommend any of them?
I played:
Dawn of War
Pretty good RTS actually. Graphics are sadly a bit too dated for my taste
Dawn of War II
RTS where you don't build bases but just produce and micro your troops.
Instead of elimination you capture and control victory points.
Very different from most other RTSs, but because of that, also an acquired taste.
If you don't care about single player campaign, I recommend "Retribution"; it's the newest and has the most races and stages.
The different versions aren't expansions that gets integrated into the main game, but separate games.
Space Hulk
It's pretty much a 1:1 version of the board game.
But it's difficult and clunky to control. The marines are slow as heck. Graphic is very samey the whole way through.
It's all dice/random based just like the board game - but unlike a board game I don't like losing in a video game because of bad luck.
Blood Bowl
Do you like reading and understanding a whole rulebook before playing a game?
Good, because that's what Blood Bowl feels like...
Once again what seems like a 1:1 version of the board game.
Where SH just didn't really work for me as a video game, BB is even worse because the rules for the game is just more complex.
Not action packed at all!
