For the most part the game is pretty easy, but there are definitely a few things it would be really nice to edit like the skill pool, friendship levels (easy to grind go-home club, but not as easy with musicians due to highere level enemies taking longer,) and inventory management (I don't actually need or want 500 of the same attack+4 item. One is sufficient as a minimum to complete quests.)
Edit: So apparently you can get rid of stigma -- you just have to select them (even if only doing one.) It even gives you skill points. However, there are things that use an insane number of points like unblocking a character scenario. (I have trouble pretending not to be irritated by Stork or going along with the con man.)
