I must agree with Attan on that one ,Imagine if a game developed by Construct could be sold by an upcoming games company and that game got as popular as tetris for instance ,Most people would kick themselves because they missed such a great opportunity.Life is all about risks and if we just say no to every opportunity that might come along we would just remain annonymous forever.
I know i had quite a few dissapointments with gamedev over the years but i always get up and search for a new opportunity.
