Cool and Good.

I mean, thats basically what OpenRA is. Or OpenMW. Or many other indie games where they build a modern engine for old assets.

Except OpenMW and OpenRA don't charge players for access/extra content, they only accept donations and give everything away for free otherwise.

Good point, they absolutely should
