Sorry but that difference isnt that huge...not brag worthy xD.
Devil May cry aint the same without this guy (even if he did make the disaster that is DMC2)
Only reason(s) why MGR sold better than DMC was
1. DmC was developed by Ninja Theory (l0l) (the design goes well with this reason)
2. Metal Gear is a bigger series than Devil May Cry.
Not that huge? First week againts first MONTH. Kojima already talking about a sequel.
Oh I thought it was first week for both XD
Again my reasons still stand though as bolded/italic/underlined
