Online games need to be joinable

[LaRock O no Lie]

I can't say much about the online... but it will not kill my MP gaming if there is no joining during a match.... but hey how about you give examples of games that are dead because of a lack of said feature?

I can't think of one off the top of my head, maybe you could enlighten me as to which games died soley due to no in game joining?
*not trying to be an ass.... but seriously... I can't think of one.*
