I find that when I play Spiral Knights sometimes it can be a bit crowded and the levels seem repetitive.
Well, I propose that players should be able to make their own levels or servers. A player-made server would be similar to a normal server, but the creator can choose who to let in and he could also have some degree of customization over his server (i.e colours of buildings, npc dialog, etc..). It should cost about 250 energy to rent a custom server for 24 real-time hours. You could also have the option to permanently keep your own server for 2000 energy.
You could also make your own levels. The player could decide which enemies are in his level, what the theme is, what treasures are in boxes and if there are health boxes, bosses at the end of levels or merchants in the middle of levels. You would also have the opportunity to name your level. Players can rent a level for 250 energy for 24 real time hours. Just as with servers, you could permanently keep and customize your level for the price of 2000 energy.
So, that's my idea.
When I read that, all that came to mind is this....
"let us pay 250 energy to create a level where we can make a massive amount of crowns, get the best loot in the game, and buy up all the CE from the market"
Seriously?
