Glad someone wrote this list (even though I myself am someone partial to bandits and a new dimension or two). A lot of these suggestions are not easy to code (speaking from someone who has been doing Java for almost a year now, along with a few years of other coding experience) and those that are can quite easily unbalance the game. This thread should get stickied with a required reading before posting on the suggestion forums in my opinion (I will however settle for the former).
Also bump.
