The game value is 70$
No offense, do you really think that you can charge MORE than what Triple-A games cost? Even console games cost less! And since you're selling it now for $10 and still no one buys it it can't be better than best selling Triple-As, right?
I understand that it might be good for starting indy game although it doesn't look enough interesting to me - but I've never been into quest games anyway.
But the fact remains that even if someone would want the game(s) you're paying peanuts. $70 would get you 2 hours of my modeling time if we go by any professional artist charge rates... and good characer take about week minimum if we're talking about design, low-res (<5K tris) mesh, UVs and some sort of diffuse & specular maps.
