Well, Freelancer was awesome. It was unfinished and didn't have half the features promised, but boy was it awesome. I'm confident that whatever Star Citizen ends up as, it'll at least be fun to play. And unlike with Freelancer, they have a way of further developing the game after the general release. Back then, patching content updates in was simply not done (expansion packs were major affairs), but with an MMO like SC, that's the usual way to go. It's unlikely to have all the features promised at "release", but they'll probably keep updating it well after that. After some years, it might end up with most of the promised stuff added in.
