This is a late response and I'm sure you got more information about the game since posting this message, however, I'm going to answer anyway :-P.
I have Twilight Struggle. It is a esay game to learn. The rule book is only 8 pages. You can sit down and set up the game and read thought the rules as you go. You'll have it in no time.
It isn't a wargame, though, but is fun anyway.
