Super Mario Maker prompted years worth of requests for a similar The Legend of Zelda Maker, a game that would let fans create their very own temples and dungeons, and while Nintendo hasn't gotten around to it yet, we might not need the company to even bother. An indie dev's halfway there already.
One-man studio Ki3 Games just released a free demo for Temple Maker 64, which is exactly what the name suggests. On one hand, it's an intuitive and really easy-to-use level creation tool fit for making large, interconnected dungeons or short, sweet challenge rooms. On the other, it's a third-person adventure game so clearly reheating Ocarina of Time's nachos, only this time with fan-made spaces to untangle.
