Any of the classic era Tales games. Destiny DC/2 both finally got fantranslations, but Namco keeps teasing that they want to bring over the games the west never got. Eventually. Someday. Maybe. Hopefully by the time I finish the rest of my JRPG backlog.

Re: Super Metroid, it's a short enough game that even if a remake does happen, I'd say it's worth playing the original now and then playing the remake too whenever one happens. Though I'm also hard-pressed to see what a remake could bring to the table honestly, it's pretty much perfect as-is. Not like 1 and 2 which have aged horribly and needed a complete overhaul. I think I'd be concerned if they tried to mess with it.
