This World Shall be mine

I was always the best at everything, nothing ever interested me, nothing other than strategy games and MMORPGs where I really had to sweat to get good, but I became the king of them all. Now I've died and been blessed with life in another world with a strange power, finally something interesting. Just like the games I've mastered and conquered, this world is a full plate, fantasy creatures, magical powers, wars and disputes, the struggle for power, everything that interested me, just like everything, I will conquer this world, whether by brute force or ruthless violence, but this world shall be mine!
