Beyond Good and Evil 2
Now this is what I been looking for in a game for years, a game where you can fly seamlessly from space to planet surface. Jump out of the space craft and walk or drive around a city and I Really like the look of the city's from what been shown sofar, very fifth Element. not too crazy about the Star Fox barrel roll fighting antics, plus it seems to be some sort of online game but they say it can be played as a single player game.
They only shown one planet but it looks like theirs another six or so in the game as the game takes place in one solar system.
30 mins of gameplay with comments from the devs
Oh yeah I forgot about this one, the early videos of this do look good. If I were them I would wait until next-gen is released as well, gives them time to get everything right. Looks like there is a few planets in this solar system and the size of the explorable area on the planet is huge (that one planet in the demo could be a whole game in itself nevermind multiple planets. I will definitely be keeping watch next summer for the updates to this one.
