I don't think the games are that badly outdated. If you enjoy turn based combat it can be a lot of fun. If you don't like turn based combat you won't have fun no matter what. And keep in mind it's only grinding if all progress stops and you have to level up to proceed. Dragon Warrior 1 on the Gameboy Color is a nice short game to dip your toes into for an 8 bit experience that's fairly streamlined.
And by awesome I mean totally sweet.
