While i regularly throw $20-$50 into game kickstarters, I stayed away from both Star Citizen and Elite Dangerous when I saw how hyped they were. Nothing good was going to come out of that.
Personal statistics: 19 kickstarters backed, got a finished product on 9 of them so far, 2 more have builds that show everything is on track. Everything I got was acceptable, with at least 7 being good or above.
Also, ALL of them were late delivering.
Not bad, will crowdfund again. Never $4500 though.
