The latest Blood Bowl PC version game out a few months back. It was a download only release but scheduled for in store release, I think, this fall. It includes 8 races. More are to follow. You can play online as well. This is the same as the Xbox version.
There are 2 modes: traditional which is just like playing the board game, and real time which is not played in turns. I have not tried the real time version as I love the board game and playing a computer version of the board game makes me happy.
As for other GW games, I am TheMasterGamer, :-) I have run games of all sorts for local gaming stores for years. I once ran a game of Adeptus Titanicus/Space Marine/Epic 40K over a weekend recreating the Siege of Jerusalem by the Romans in 69AD. By recreating I mean that when I design scenarios for a game I often base them on an actual historic battle (terrain layout and the like) but then place them in the setting of the game for forces available.
The table was 8' x 20'. A normal game is between 2 players with about 3000

in forces each. We had 24 players in the game. There were over half a million points in troops involved. It was massive, and it was massively fun.
