The game is somewhat of a mixed bag for me but for some reason I really liked it, mainly because of the turnbased combat, the very good physics engine and destructable environments, and the general feel of it being a WW2-based dungeon crawler. There's a couple of issues I had with it, but I can't help enjoying it.
Right now I'm thinking of buying the Sentinels expansion, but I can only find Silent Storm Gold which has both the original (which I already have) and the expansion. I suspect I'm going to purchase it anyway, but I'll be trying to sell off my copy of SS too.
