Stage 1: Players come spend money on gralats and enjoy socializing with friends
Stage 2: Players begin to get bored with current content but still play
Stage 3: Players begin to vocally express their dissatisfaction with the games direction on a dead online forum
Stage 4: Players leave after realizing nothing will ever change and that they just outgrew the game.
Stage 5: New players in Stage One simply replace the older players and the cycle begins anew.
A game built primarily by people volunteering their time and getting no monetary compensation will never grow, it’s that simple. Take Graal for what it is and if you want a game with some depth then you’re probably better off finding a new game to play.
