Another thing that I realized in relation to this topic is that the technical issues and incompatibility with modern hardware are other factors that are making the game less popular. I'm sure there's plenty of people who just gave up on the game because they couldn't get it to run on their PC's. We're fast approaching the point where GPU drivers wont even let the game run anymore, and there wouldn't be anything we can do about it. In that case, there would be no older driver to roll back to, so the user is left with no solution for making the game work.
That incompatibility falls on the shoulders of 16T. See, they recently updated the Em4 Deluxe listing on Steam. I am sure they still have access to the original code - they could have at least updated the game to be more friendly with modern hardware before putting the damn game up on Steam.
