Did Monster Hunter World outsell Halo 5 on the XB1? If so I didn't know that and congrats to Capcon. If its comparing all systems MHW is on to just Halo 5 on XB1 than its as simple as saying "TOYOTA sell more cars to Ferrari" comparisions.
At least , some jrpgs would outsell Xbox's biggest franchise .
So what is niche ?
Tell me Xbox people.
