How do you import your save from one version of this game to the latest?
Also if you would buy this game would you get the latest version and a new version come's out would you have to buy it again or do you get to download it without paying?
just copy your save folder from the old version to the new one. And no, you don't need to buy the game again, you will always have access to the latest version of the game with one purchase.
But seriously, if you click the down arrow next to your user name at the top of the page, you'll see a drop down menu, click "My Library" thats where all of your downloaded and purchased games will be.
