5-6 years of development? Too late. That said I never had any issues with Halo MCC in the first place, so don't know what's supposedly been "fixed". Wouldn't give it a 10/10 though, Halo 3 could potentially justify that score, the Halo 2 remake as well. But Halo 1/4 definitely don't deserve a 10/10 so with them in the collection they'd drag down the score.
@poll I've never even heard of super mario all stars, so yeah Halo MCC is probably better.
Bet Shiken that COD would outsell Battlefield in 2018. http://gamrconnect.vgchartz.com/post.php?id=8749702
