50xp a game minimum. Not bad. Takes 20 games to lvl if you don’t finish any other challenge. Starting from 0 and going to 100 it would take 2000 games. If you average 10 minutes a game (Pulled this number out my -Yoink!-) should take 20,000min/334hour/14days. You have until May 2022 to accomplish this. Quit complaining and go play Halo.
