No one claimed it was as popular or as big as those games, whoever did is insane... but it is looking amazing and probably will help in sales, just not a huge impact like those games as is common knowledge. Don't say it's overhyped by pointing out it's less popular than the 3 most popular franchises on consoles (FF, MGS and GTA) outside of Halo in the US.
Thanks to Blacksaber for the sig!
