I was gonna hold off on a reply until I had a bunch of stuff, but one thing has been irritating me greatly. The encounter rate. Way too many enemies. I just visited Rocket Town and have not seen Enemy Away yet. This is probably a materia that could be dropped early on in the game to ease enemy encounter woes without any drawbacks.
A couple other things:
1. Palmer's step mine never did anything, it just said "but there was no step counter" or something to that effect.
2. I fought Palmer twice, and stealing from him in the second fight yielded a different item. I don't know if this is a bug, I just don't recall enemies having different potential items you could steal.
Hopefully if it's not a bug, then the items you can steal aren't good, because it would suck if you lucked into stealing a bad item instead of a good one.
3. I'm not sure how sense works, but I think it gives misleading results. Many times I base my attack on what sense returns, and it yields poor results. I think I have seen enemies take no damage (or worse, heal) from elements they are supposed to be weak to, and Titan seems to miss against guys who are weak to earth (Titan just misses a lot in general).
4. The Materia Keeper, or whatever his new name is, cast a spell which caused several effects on himself, one of which being death sentence. After his time was up it was revealed that he is immune to death. So what was the point? I had kinda thought it was a "You win this fight by not dying for a period of time" situation, but nope.
5. Vincent did a crazy jig upon seeing Sephiroth/Jenova at the mansion (He was supposed to walk calmly like my other companion). This one was amusing.
