I think I have decided for my lifestyle I need to get in a bit more on this sort of mixed miniature game vs board game (I guess Hero Quest did this a loooong time ago, GW never really had versions available when I was playing, apart from Space Hulk). No need to prepare tons of minis, no need for transportation of hundreds of models, and can easily bash a game out in 3 hours or less from when you turn up.
I am simply too slow at miniature games to fit them into a normal evening!
I played a game of The Others with Matt, Midaski's son, last night and really enjoyed it, although after the fact find out we had been playing the rules wrong making the heroes too powerful (not my fault- Matt read the rules and guided the game!). The bonus for this being that many of the "sins" models could be used as some sort of chaos demons, which I think Matt plans to use to expand his 40k army to playable sizes.
