If we kept playing same quality of game for more 5 years , the game may die
But , what if we added stuff , adding more materials , Liqueds . Flames . Explosions . Remove useless stuff , adding new free form object creator.

All that can change the game from inside without changing the quality in the outside .

But if we changed quality from the out side , that may bring High level of quality player as known as hard core players like mr.snake.
