Given the Gamer ability after shattering a crystal inside a game, Jon's world is upturned as he is thrown into a life he considered fantasy. Making new enemies and encountering a god, he cannot escape the quest which is forced on him. Different worlds and different situations, can he come out on top? He's neither perfect nor a saint, he is Jon. Welcome to Gamer.

This has been dropped, I didn't like the way I forced a few plotpoints and I lost my notes on the story itself. Read below if you want to be spoilered.

As far as I recall, he would change race into a higher human after using a spell to overload his mana repeatably until his body forcibly adapts, he would train up his rift usage spell with some better targets than God's Realm because he keeps hitting his stats limit until the cost lowers enough that he can actually grind it. His world is being invaded by multiple worlds, so the god had many backup plans where a lot of people went into their own fantasy settings and came back to defend Earth.

Jon never is the strongest one out there, he has to keep grinding and grinding before he gets stronger than the other heroes, and at that point the invasion is nearing the final stretch. Jon's two biggest advantages is that he can keep grinding without hitting a cap he can't evolve, and that even when he is eventually killed. He would have respawned in the nearest 'Safe Zone' after dropping a level and everything he did to gain that level.

I also had a bunch of ideas for mini-arcs where he would play in multiple worlds in multiple situations, not that great of an idea in retrospect.
