caveat emptor. no one is forcing people to buy a thing that they know is incomplete and may never be complete.
True. The problem is that there enough people out there that will buy incomplete games thus ensuring that the practice continues. So, if it's the selling of unfinished games that one is opposed to, which I happen to be, then my not buying it won't really "solve" the problem.
I once prayed to god for a bike, but quickly found out he didnt work that way...so I stole a bike and prayed for his forgiveness.
