Not bad, but not much room to explore, pretty straight-line
Also hate when they put two set pieces in the same mission, forcing you to replay the one mission for both pieces. Worse when you're trying to equip multiple toons, so are looking at 4, 6, 8, or more replays. Once per toon would have been fine, save the next set piece for the follow-on mission. A couple other FEs have done this, which sucks. Ok to put a ground and space piece in the same mission, as you could be aiming for either, but putting two space pieces in the same mission is lazy/boring.
