Good question, I already accidently payed a game that gives free versions at some point, but what did they do, they released the updated version as an extra game and i suspect that I was made the idiot there.
This might not be similar, but it sounds like it would be all part of one game.
The original was free, so I'd fully expect this dev to make you pay for 2 and 3. They've returned with a vengeance after the game was banned from everything lol. He ain't doing this for free this time.
