I think we was much clear about "why" the change and to launch it in the market...The main vision of this model is to benefit not one or two games, the main vision of this model is to benefit all ecossystem of blockchain games

First of all, this crowdfunding certainly will work like an escrow where the funds collected will only be released to developer if certain criteria are met?
