I'd like Quake 1 to have a true sequel.

Age of Empires, F Zero, Metroid, 3D Rayman and Starfox ....oh wait.

Wild ARMs, specifically a TRPG like XF.

Wild ARMs XF isn't the best in the series, by far actually, but if XF it had a few tweaks in its system and didn't have one major AI flaw, it could have been. Atleast gameplay could have been. Most stages are created so that this AI issue isn't such a big problem, but if there's a height difference, a building, etc, where the enemy would have to go around to reach you. If they can't reach you in a single turn of movement, then they'll get as few spaces away, even if it's not really close, it's only close by the amount of spaces.

Even with its issues, it's one of the best TRPGs ever imo. 

It'd be awesome if we got more Anime games in the vein of DBZ LOG2 and Buu's Fury.

Bully? Really? That game was so weird, gave me the creeps...

Anyways, SIREN and VALKYRIA CHRONICLES

Take a look at DB: Xenoverse, its being worked on by Akira Toriyami and Dimps (creators of the DBZ: Budokai series). Its going to be awesome.

I can only think of The Legend of Dragoon, Valkyria Chronicles, White Knight Chronicles, and Shenmue because they stood out to me the most.

Banjo, Conker, Crash, Spyro ( that Skylanders shit doesn't count), F-Zero, Mario RPG, Mega Man, Chrono, etc.,..

F-Zero, Metroid, Custom Robo, Suikoden, Banjo, Valkyria Chronicles, FF Tactics, Age of Empires
I feel like everything at the forefront of my mind has aready been mentioned...

EDIT: Mother. And if The Last Guardian was actually part of a "Ico" franchise, then that... Mirror's Edge is coming back, for better or worse.
Radiant Historia.
Maybe TWEWY.

MOTHERFUCKING PERFECT DARK!
