And how is this a steam issue, tons of games get outdated if ppl want other graphic or are done with the ways they are made.

I bet you don't like the reply, but if it was so easy to make a top seller game, then all will do so.

ps.
I know only a little about it, if it was not because behind the how a game was made, they use alot of research and try AIM GOAL with what they can afford, and dont promish alot of BS a game engine can't handle. ( to actual release a game is a goal in itself. ) you can find 100 if not millions of project that get cancel or dropped. wiki page are filled with spin off that never seen the day.

And i have to respect game devs that even dare pull the plug. then its over its over.

also why AIM and Goal and affordable most be right. ( sounds simple on paper or in a chat )
but i bet so many things can go wrong then money dry out.

Get a copy of Unity, Godot or Unreal and get working on it!
