Herzog Zwei baby! Man, why didn't we ever get a sequel or anything to that...

Also enjoyed Warsong immensely... it's still the only game from the Langrisser series to come over here.

I could never afford Phantasy Star IV, but I did love Phantasy Star II and (to a lesser extent) PS III. Amazing that they put both (plus PSI) on one GBA cart. Sega, where's my GBA Phantasy Star IV, and when are we going to get a V, instead of all this online nonsense?
