I am really missing the cloud save functionality of Steam in Terraria, so I implemented a work-around. I tested this on Windows7 and it works, though I assume that once cloud saves get implemented there won't be a need for this "trick." Again, this is just a trick and not an official means of getting around the lack of Cloud Saves so try it at your own risk, back up your files, pay your life insurance, etc. By linking your Terraria user data to a dropbox account, and subsequently linking the dropbox share to a Terraria installation on another computer, characters and worlds become portable (up to the in-game character limit, and the size restrictions of your dropbox account. Resources: Microsoft Synctoy - Download A Dropbox Account - Sign Up Steps: 1. Install and configure Dropbox and Synctoy with default settings on each machine you want to have access to your Terraria user data. 2. Use Synctoy to sync the ~/Documents/Games/Terraria folder to a Terraria folder in the Dropbox share on your main PC. 3. Repeat Step 2 for each subsequent system you want to give access to. As long as you keep the ~/Documents/Games/Terraria folder synced when you finish playing, or before you start playing you'll have the most recent version of your characters. I didn't take the time to try to automate the sync process, but I can figure it out if there's interest. 4. Profit! If anyone has any suggestions or anything to add feel free to comment!
