I would like to make a game in Blender with their Blender Game Engine, but i want to have a Minecraft-like graphics.Is it okay to make that? The game is NOT Minecraft (gameplay, mechanics), only the graphics.It's a totally different game, but for some reaosons, i want to use the characters on the game (mobs) like the creeper.
