So guys, I see by the poll so far, you guys want me to either make a puzzle platformer or an RTS. We still have a week and a half left to vote, but so far these two sound like fun. RTS mechanics would be a fun tutorial to make, as there are really no tutorials out there that I have seen myself, and a puzzle platformer is always fun to make.
Ideas are already starting to pour into this skull of mine, but I shouldn't get carried away. A week and a half of voting can change things around quite a bit.
