I understand that the newer version of this game has several changes and more gameplay, but I think it's a bit unfair that we have to buy the game again if we want the updated version of it, all because you decided to switch the platform you distributed on. Not only that, but the updated version isn't even available for those on MAC so anyone who doesn't have a Windows or Steam console can't progress any further with this game. I understand wanting to expand your market, especially after a game becomes popular, but to just up and leave the original community that gave you the purchases and downloads needed isn't painting a good picture.
