Final Fantasy IV [iPhone]
Keep it simple in action as front rows are for fighters, back rows are for the mages. Back row members take less damage from physical attacks, so keep the weak ones back.|
Exploring dungeons completely - watch the percentage counter on the lower touchscreen - gives you a few items for your troubles, and is almost always worth doing.
When grinding through easy battles, just pop the game into auto and allow your team to do its thing.
