I would play the hell out of a Tactics 2 that involved similar gameplay and a similarly dark plot, even if it wasn't a direct sequel.
Tactics , cause I want more brooding politics and see more of Ramza's Ivalice.
Tactics Advance, it's more fun and doesn't take itself as serious and I love the various races!
Neither, Squenix should make a new series set in Ivalice not attached to either series directly.
Both, hey the more the merrier and then we don't have to argue over another Tactics Vs TA
