Konami's online games - like Metal Gear Online - have really suffered from the company's insistence on using two proprietary online IDs, despite the fact your console already has one. Looks like that practice may be coming to an end.
Yes, up til now if you wanted to play a Konami game on your console, not only have you needed a 360 or PS3 online account, you've also needed a Konami ID AND an account with the relevant game. So three accounts. Silly. So silly, in fact, that even Hideo Kojima totally hates the scheme.
