I think it would be great if we could save energy by turning on ads. We could have a toolbar that has an option to 'turn on ads' and when you turn them on it will take less energy to explore and craft and other things that take up energy. That way threerings could still be making money from ads and players get a discount. my thinking is that most players would turn ads on to save energy.

Also, there should be some way to get a permanent weapons slot, through buying or unlocking an achievement or whatever, but not through real $$$ because that would give some players an advantage over others.

There should also be a pvp arena so players can fight, cause my friends argue over who is better, and there is only one way to find out! Also, it would be more fun if we could battle eachother rather than just fighting co-op. There could also be games, like football or something, where you have to score in the goals without getting attacked by the other team, or there could just be team deathmatch games.
