Double or Nothing

What's a guy to do when he's been killed and a bored God gives him game powers with five wishes and a free trip to the land of breast and dragons? Drag his girlfriend to help him, become overpowered and live like kings and queens till their end of days. And maybe pull a few pranks when he's bored. Big Harem, lemons, neutrally good protagonist with a bit of an edge. Gamer.
