I've been playing Spiral knights for some times now, as everyone who first start out on this game, we all know that its annoying how when we run out energy, and when we run out of energy there's nothing else to do. Even tho I do buy energy but just speaking for those who can't.
Anyways I would like to so some mini games and arenas on the surface of Haven like a dueling arena and guild wars, where people can just do some PVP.
If a game only allows you to actually play the game underground and only be able to face AI monsters, than its quite empty when your only fighting the same thing over and over again.
If be more fun if there's some sort of Pvp place where people can fight with others players using skill and tactics, hence there would be a better reason to play the game and level the gears in the depth.
Overall, if the game allows you to test you ability more than just repetition AI monsters, than there's a better reason for people to play.
Hope you guys make something like that and host tournament events, or this game wouldn't have much meaning to it than just killing bots.
Please post other pvp suggestions :D
