ZombiePirate and I managed to play an inaugural game of the Speedball2 40k Bloodbowl mash-up general GW trolling Dreadball yesterday. It was the not-quite-space-marine Trontek 29ers vs the not-really-sisters-of-battle Void Sirens.
Fortunately we had both looked at the pretty pictures in the rulebook which is always a plus when trying out a new system. There were naturally some high levels of rules lawyering and checking owing more to it being our first game rather than us being competitive twelve year old at heart.
Overall it was a positive experience. The game system seems very intuitive after a few goes, and the whole thing should flow very quickly after a few games. The game itself is very fast paced and good fun. Hopefully it can become a good staple game.
