I liked it a lot at first, but the slow pace kind of got to me. I guess I just like shorter missions better for these kind of games since I love Shining Force.
Concentrate on levelling your scouts, rush Alicia and Aika to the enemy flag, use grenades to force any defenders out of cover/crouch position, shoot them all in the head, capture flag. 2-3 turns max on most maps.
If you want to vary your strategy, you may replace Aika with another sufficiently cute female scout.
