I have never quite understood why people don't follow this one... the incentive to finish the game is /money/. At present, Star Citizen doesn't turn a profit because it uses money it takes in to fund development. There's no benefit for investors, owners, etc. until the game comes out... which is part of why it's kind of impressive that Chris is focused on his vision instead of deciding the game is done and collecting a big check.
ehhhh maybe, I watch gameplay clips from youtubers here and there, if chris said that is it, and he was done and released it, the game would be unplayable for a lot of people. I do have one co worker who plays the game here and there every time there is a massive update, I asked him what he thought and he called it "a cool tech demo for a future project."
I truly hope it turns out to be a masterpiece but at this point any consumer of star citizen that wants to complain, has plenty of valid reasons to do so. we have come so far from the original kickstarter pitch that it is not even remotely the same game. At my age I have next to no interest in multiplayer games at all. I have pretty much regressed to only playing adventure games and rpgs, if I ever get around to building a new pc, id only be interested in the single player.
