I've played both FC Rommel and FC Alexander.
There's a review of mine over at That Other Site
TM for
Field Commander Rommel, which elucidates pretty much everything about the game, IMO.
Alexander is much the same as Rommel, except...you know...not so much halftracks and 88mm guns as sandals and swords.
I'd recommend 'em both. But, understand, they're solo games, though I can't recall offhand if there are any rules for 2-player games.
