Was Live a full priced $60 title? These charts are revenue based. So more expensive games can chart higher than others even if they sold less copies. Metroid for example was the 8th best selling game of the month according to Nintendo (and no they can't lie about that, they're a publicly traded company) but it charted at 12 cause 3DS games are $40, not $60.
Those numbers would be incredible.
I'm not sure what XCOM sales numbers are but in terms of console games, I'm pretty sure that would make Mario + Rabbids the best selling SRPG/TRPG ever made.
Gonna be interesting to see where it places. Shadow of War will have been out the entire month on 3 separate platforms with far bigger install bases and Assassin's Creed is out on the same day. Not sure Odyssey will be number 1 for October but it will have ridiculous legs. Odyssey will chart until well into next year.
Halo Wars is probably the biggest.
