After consulting a walkthrough and some forumites (forummers? forumians?), I came to the conclusion that Star Ocean: Till The End of Time has the hero spend the bulk of the game on medieval-level planets and stripped of his own starfaring culture's technology. It sprinkles some sci-fi in here and there, with a chunk at the beginning and another, larger one at the end, but for the most part it consists of straight-up swords-and-sorcery.
So into the archives it goes. I'll play it when I have no other games worth playing.
Now, as for GRID... it'll take a long time to get tired of that one. I did not have a lot of play time, so I ran the Muscle Car Classic again, and won handily. Tons of fun.
