I’m torn about them. On the one hand they free up the combat design to be as wildly different from the exploration as it wants. Which can result in really creative stuff. Favorite examples are Undertale, MegaMan Battle Network series, and Tales series.
But on the other they interrupt the flow of exploration, the music, you forget where you were by the end of combat and they can be very annoying if they happen to be common or just as you’re about to leave an area. The consolation prize of growing stronger with every battle only helps so much.
That’s a good point. Trivial encounters feel like a grindy and annoying waste of time. I guess it doesn’t necessarily have to be that way though.
I also think Final Fantasy falls too much on the old turn based choose from a menu, watch a cut scene system, when there was room for something more interesting. That’s just taste though I guess. I haven’t even played any other than Final Fantasy I and Tactics Advance maybe they changed.
