If they collided, universes, we'd notice milleniums in advance when our gravitational systems go haywire - I'd hope a few thousands years is enough time for people to make mends and figure a solution lol
Numbers: Checker Players > Halo Players
Checkers Age and replayability > Halo Age and replayability
Therefore, Checkers > Halo
So, Checkers is a better game than Halo.
