I like the idea of adding a building game, i just think it might be something other than what you have suggested. You may want to make a more refined post rather than adding updates left and right forming a blob of dis-organized thoughts, not only does this help players understand you more but also makes your idea seem better and shows confidence. Also people who just say -1 or things like "i'm not a fan of this idea -1" just why? if you don't like it mark no on the pole if it is an option and move on, if it is a good idea it will get more replies of how to make it better, more popular posts will be seen as more likely to be accepted, adding your little "-1" just fills space and adds a little score to your messages, try typing something useful to them on why it's bad or how they can make it better.
