Star Citizen's already been worth the money I've spent on it. Arena Commander, Arc Corp, hangar, racing, now 2.0 with quests and FPS, definitely worth the minimum asking price.
Having a lot of fun with 2.0. It's been running really smooth today. And it's seriously awesome to just watch the space and planets in this quality, then standing in the shadows on some space station watching a massive dogfight above you... and ambushing the winners with an assault rifle when they land. If you can stomach some crashes (average game time around ~70-90 minutes if you know to avoid certain things), it's worth it already. Or if you're just into dogfighting, Arena Commander rarely if ever crashes.
The ships+EVA element adds a lot to FPS, enemies could be in literally any direction; and you can use any direction to approach as well.
