The game mechanics should be simple, as much i expirienced youre in the right path for now. I more worrying how you guys gonna balance the game dificulty as lvl-ing and gearing. If its too izi the game will be full with kids and if too hard most of the players will be grown people. I personaly don't like to see evry person who runs a dungeon gets the same items as me i like to feel like my hardship was more worth than the other person ones. Ofcourse there is luck too sometimes dosn't matter how much you try you can be unlucky too.
