So, I couldn't find a thread for this but I always find it a good way to spread knowledge of our favourite up and coming games from small developers or teams.
First off:
Infinity Quest for Earth
Beautiful game, procedural universe using seeds to keep down data costs (Huge galaxy of 200billion full planets, asteroids, moons, gas giants, stars, pulsars, etc. stored as numbers in a massive equation). Did I mention it's a sandbox mmo with newtonian physics?
Still in development, maybe beta within a few years. I've been following it for two years. I am excite. There is a prototype that came out awhile ago for the combat system. It's really old now (can't compare to the actual engine much anymore) but it feels so good to have newtonian dog fights.

Another is Aero Empire.
I found it through a clanmate from TBO who is the concept artist. He does some really good stuff for Infinity and his work for Aero Empire is also excellent. Kinda Jules Verne steampunk meets asian design and cell shading.
The world is covered in a massive, very dense cloud layer and the only inhabitable parts are mountains that pokes through. Dirgibles and a few little glider-like fighters are your vehicles.
