Whoever said that, is probably insane, because as Frogboy said, Demigod was 1 of the hottest games in the market, for the first 3 months of its release.
Thats why I bought it, and I wouldnt spend my money on something else if I could get it back.
I consider Demigod a Success-Fail game though, because while it sold many copies, was and still is an amazing game, it gets shadowed by the many bugs and problems it still has.
Just my 2 cents
