You all forgot one important fact. This gen only one gran turismo game was released and that was gt5. Gt6 don't count yet. How many halo games were released this gen? I think halo 3, halo reach, and Halo 4 and this is not counting other halo game during this gen. Of course halo sells better. It's 3 different halo games vs one game this gen.
Halo is very popular in the United States but its only a niche in other countries. Gran turismo is universally popular worldwide. They have a reality show too GT academy that people all over the world compete.
