My mate is a big collector and player of Warhammer 40K. I've seen it been played before and I've even been to Warhammer World with him. (It's only down the road from my house
) I think its really intresting. The artwork and the characters are really unique but I'll never have enough time or dedication to play.
I've always wanted to play D&D just to say I've tried it. It looks pretty fun even know I've heard it takes longer then you think.
