What's funny, is I kinda like the squishie ones from the PSX version better. Hee hee, they're so cute. XD
But either way I don't mind on the sprite thing. If the scripts are the same, I'd be more interested in ripping the "full voice" aspect of the PSP version and applying it to the PSX--though for some reason I get the feeling that'd be a nightmare and a half. LOL
Actually I like them do. I don't know why I just do.
I'd say the best way to do it would be to use the PSP sprites for Cress and the gang and use the ToE sprites for monsters. Thats just me though.
