Well, spent about an hour so far with Grinsia. While I love the Auto-KO mechanic in general, it doesn't work quite as well in a game with random encounters as it does in a game with visible enemies like Earthbound. Since, starting at Level 3, I could pretty much just wander back and forth in front of the starting town, auto-winning 80% of battles (and obviously even more as my levels went up), and quickly gain like another 4 levels.
Granted, I suppose, it's not all that much more different from actually going through battles where you're not getting hit, and defeat the enemies before they have a chance to do anything. But, still, I don't know, just feels like I could do it with my eyes closed (perhaps since I was doing it some of the time with my eyes closed), which makes things feel a bit less interactive.
Still seeming like a fun game. Although I still haven't actually left the area right around the starting town yet (what can I say? I like grinding).
Apparently there's something worthwhile awaiting me though:
