1 & 2 over 14.5m combined.Halo Wars, Spartan Assault, Spartan Strike, & Anniversary are irrelevant, all of them probably sold <5 million combined, so that leaves ~45 million between Halo 1, 2, 4, Reach, & MCC, we know that MCC sold <5 million, & that 1 & 2 sold <10 million, so Reach very likely sold ~10 million as well.
3 & ODST over 14.5m combined.
MCC < 5m
That give us close to 35m.
I'm sure Reach and 4 did at least 8-9m (10m is not out of question but not a lot over that)... that leaves about 10m for 1 Anniversary, Wars and mobile games... I can see these mobiles game with 2m each and War with 1m.
To be fair the only game MS said it crossed 10 million is Halo 3... everything else is speculation.
