On the topic of CAS, the enemy columns more often than not disintegrated before I could designate targets for my two A-10 strikes. Otherwise, I didn't even consider loosing the CAS about three quarters into the game I believe but by that point almost everything was over with.

As for FATE, I'm unfamiliar with it, but that's most dice or tabletop systems for me, at least the non-Warhammer ones. As for alternative ideas no matter the system, Napoleonic line warfare definitely appeals, albeit I'd be willing to do practically any wargame so long as you were running it [@Gunther].
