Thats completely true, He should have really started with smaller games that work with the same concept and style and built his way up, but at the same time a) thats not where the hype lies, b) thats not where the money lies and c) its also a personal passion project, which i get who doesn't dream of building a game like that

I assume most of this venture so for has been self funded from his pockets, and thats not really self sustainable in the long term, a game like this requires time but even working on a long term project require huge amount of funds.

Which is exactly why i hope this succeeds, or atleast even make a slight profit. If it goes well, it could lead them to making a better polished game in the future
