People, be serious.

Selling your game for 50 bucks is actually pretty good for an indie. If you need thousands to let go of your source code, where all the copyrights are still yours, you are way too attached to your own creations.

There is a problem though.

I'm pretty sure you can't sell on your models bought elsewhere (i.e. DEX-soft), so the buyer needs to get them himself, as if I'm not mistaken you aren't allowed to resell them for profit (which would happen when you sell your game with the resources). Only resources that can be included in the 50$ are the ones you as a seller have copyrights to.

Buyer (robertbruce) doesn't dictate anywhere that he will take the possession of the copyrights, so what actually is happening, is that the publisher (buyer) gives you (seller/developer) one-time payment for the game.

I still think it's a good deal for an indie.
