Thanks everyone for the responses. I decided to get Memoir '44, and just picked it up yesterday from a local game shop. They ha Tide of Iron, but I didn't know anything about it, and in hindsight wish a little bit that I had gotten that instead. But whatever is cool.
The rules seem pretty cool, and I like the little miniatures. I'm pretty pumped to play. Also while we were there my friend got Arkham Horror, so I think this weekend will be bad ass.
I'm glad you're enjoying M44! You did actually make the right decision in not buying Tide of Iron; compared to the other wargames I've played, it's not in the same league.
I've played through all the scenarios in the basic M44, and the Eastern Front - that's a lot of fun. We're going through the Pacific Theatre at present...
Cheers!
