Two Kickstarters that probably aren't going to meet their goals but I found nonetheless interesting.
Killstorm, a reimagening of the classic Desert Strike.
Racewërks, an arcade racinggame with car customization and an easy to use trackeditor, could well be a replacement for Stunts if they add loops and corkscrews.
edit:
Vektropolis is a project I will follow, it looks incredible.
Contact Vector is interesting too, a spaceship RTS that reminds me of Nexus: The Jupiter Incident.
