it would be awesome if there was a ranking/fame/ arena mechanic.... If you dont know what i mean, look for a game called Overgrowth. There are 2, the one im talking about was covered by a youtuber called Alchestbreach.... search in youtube "Alchestbreach overgrowth"... skip to the part were he shows the arena section...

I dont know, im just trying to give ideas. The game is good, needs a little bit of polish...
