I would love to see a side Zelda game that focuses on Midna and how she came to be the Twilight Prince

It could be very well done and I'm pretty sure a lot of people would love that.

Legend of Dragoon
Jade Empire

Valkyria chronicle.

hmm, alt-account? Gotta give you props, I had no idea up until now. :P

There's history and mythology there that could be explored ineed. :)

How would that work?

I'd like to see a game set in the world of Dragon Age before Dragon Age. I think the story writers are going somewhere with their story and well... I don't like it. I like the world of Dragon Age, it's setting, magic etc so want more stories in it but I don't care who is who like the writers seem to be spouting.

Also, being free from the 'decisions made in previous game' scenario would be good for developers.

I agree with everyone who said Red Dead Redemption

I'd love to see ND flesh out the 20 year gap between TLOU's 1st and 2nd chapter (that technically counts as a prequel, right? :p). I'm not sure how it would work as a game, and i'm more interested in seeing how they plan to move forwards anyway, but i'd be totally down for a book series.

The World Ends With You sequel or prequel could work... though I'm worried that if they make a new one, it won't be as good D:

Metal Gear Solid 3.

I want to play as The Boss.
