Yeah there was a lot of problems with this game, but doesn't mean it can't be worked on! Again, I really like the general idea your going for, having them blank slates is a great idea, and I get where your coming from with it, a kind of roguelike where it gives a lot of choice as to what character builds you wanna go with. Its definitely ambitious, and I'll probably play it again if you ever finish it! I'm glad to help and thanks for watching!
As for the walking speed, I only removed it cause I was annoyed at having to repeat everything again, the areas were small so it wasn't that annoying doing it once. But doing it again was a bit much however...
I've seen stealing in other RPG Maker 2000 games, it should be pretty easy to implement! Simply add a switch to conditions in battle events in each of the troops you want to use it in, then put a message detailing what you're stealing, then add the item you are stealing! You can't choose which enemy you steal from, you just kinda steal from the group, but it's still pretty cool! Tell you what, I'll add a stealing tutorial to my RPG Maker 2000 tutorial maps for you to look over, as well as various ways you can use the Battle Events in the Troops tab to make custom skills... (I can think of several interesting things you can do with it, having mp regen, dialogue during battles... useful stuff you'd might wanna include in your games)
