Well, it depends on whether you think companies should give you the product they said they would deliver and you gave money for.
Sure, if you are a later backer you might feel as though CIG are delivering on what you paid for, but they certainly haven't delivered on what they initially promised, and by that, i mean after close to 500 million and 9 years they haven't delivered on what they said they could do for 5.5 million in 2-3 years.
Scam? Some might call it that. They have certainly lied to backers enough over the years. Personally i go more for incompetence combined with ego, narcissism, and a willingness to say whatever it takes to keep the money flowing (ie: lie through your teeth... which does make it scammy).
I mean, come on guys. What's done is done. Everyone who wanted a moan has had plenty of moans already. CIG have stated their plans for the coming months and its not likely they can say any more than that.
