How about a machine that changes your name/guild name/standard color for an energy fee? Any thoughts?
Character Customization Changes
What about limited time tokens? Like an event for a month with a special mobs of monsters that drop certain tokens that could be traded in for stuff. Then after the month. The monster isn't there anymore only the token trader. Maybe a fan based event? Like design-a-set, or design a monster, design a boss, trailer, weapon, loading screen etc. Why not involve the community in the development of the game?
Omgosh why not a huge expansion to the game. Like finally when you get the ship fixed or whatever you can go to a vast majority of new planets completely made of clockworks like this one. Maybe a pvp planet, gambling planet for slime races >:3. To be honest I don't know I'm just bored and making random suggestions. Maybe more quests with rewards or even weekly quests. "This week there has been a raid of wolvers on the base camp. Kill 20 wolvers for blah blah blah (insert reward here).
Sounds like a completely arbitrary addition that has no practical use aside from the purchasing and spending of Energy.
It will be in the next update.
