Hmmm... No, sorry I haven't. But a Crystal remake would be cool, as I've never played it before. Anyway, they probably won't make a Crystal remake because that's Johto, right?
There won't be a crystal remake. The already implemented a lot of the things from crystal into HGSS anyway. When they made the remakes Fire Red and Leaf Green they didn't make a third game, I doubt it would be the same this time.
Who knows, they might put that stuff in Gen V.Dang. I wish they would bring out some Whack stuff like they did in Crystal. Like being able to Customize your Trainer (Clothes,Hair,ect). Get your own House (like a secret base but online so you can invite people to your house and battle them or play mini games) Stuff like that would be soooo legit
