What can I say, I'm a WWII Buff (or so say people i know) and have always enjoyed war....well, everything up through WWII pretty much. I think its also a very real...thing, if you know what I mean...hard to explain. Post-apocalyptic (If i can ever spell the word) settings are always intriguing - i've enjoyed SM. Stirling's series on the matter.
I also prefer WWII Weaponry - more even playing ground (for the most part) and really relies on skill of the shooter then the ability to put bullets down range, or simply click a button like modern warfare.
Alas, I am rambling once more! At least the second time this day, and second time in last 10 minutes. But yes, some of them have potential to be small group games, though i'd rather feel more like a player then a GM shepherding people through a world of my creation.
