"Games
The last Game Boy Color game released in Japan that was also compatible with the Game Boy and Super Game Boy was From TV Animation - One Piece: Maboroshi no Grand Line Boukenhen! (June 2002). This gave the original Game Boy (1989-2002) one of the longest continuous lifespans of any console, only bested by the Atari 2600 (1977-1992), and the Neo-Geo AES/MVS (1990-2004). In the US, the last game was Harry Potter and the Chamber of Secrets."

This only solidifies the idea that a lot of games, even newer ones, were made for BOTH GB and GBC systems, creating a non-dependency for one-or-the-other.
Numbers: Checker Players > Halo Players
Checkers Age and replayability > Halo Age and replayability
Therefore, Checkers > Halo
So, Checkers is a better game than Halo.
