Star Citizen delivers exactly what it promises: an infinitely developing sci-fi starship sandbox simulator.

The pace of development is glacial? Well, yeah, this kind of project should have a thriving community of add-ons to be of any use, or have 1000x the developers/artists working on it 24/7... but they decided to follow a single vision, instead of allowing people to fly in copyright infringing X-Wings and dildo shaped ships, so this is the resulting compromise.
