Name one game or series that you wish had a sequel announced for it. It can't be a game that has had a sequel/new game announced already (like Suikoden or the new Batman games), or a game that you know is going to have a new sequel (like Madden or Grand Theft Auto, which is very likely to have a new game). It also can't be a remake of an older game (like a FF7 remake). Feel free to elaborate on what mechanics you want in this new sequel...
For me, I wish for a new Wild Arms game. I absolutely loved the western influence in an RPG, plus the music of Michiko Naruke is awesome. I wish the gameplay would retain the pre-WA4 battle system instead of the whole hex system used in WA4/5. I also liked the fact that you could cancel random encounters, and I'm not sure how I feel about the whole "search for a new town/dungeon using radar" thing.
