One of my favorite was Front Mission 3. Never finished 4 and 5, never played Evolved. But still, if they introduce a new FM game, I might die of happiness.
Imagine if they adapt to the battle mechanics of Dragon Age, where there's a tactical mode and real-time mode, that'll definitely fit the gameplay. Plus, there's tons of mechs! Or should I say wanzers. Man, you got hyped now!
