This is one of these questions again and I know this is answered by many website and this is why I come to you since I have read soooo much about it that I don't know anymore what to do!!!
My plan is very simple to be honest, I'm launching a gaming website which will have one main forum (vBulletin) and multiple mini-sites via WordPress . The accounts link will be done with vBSSO which works on Multisite.
The structure would be :
http://www.domain.com -> main page taking every piece of news from every mini-site.
game1.domain.com -> main mini-site with information and news about game1
game2.domain.com -> main mini-site with information and news about game2
According to most tutorials I read I do not need multisite but I wanted your opinion as I feel each mini-site is kind of independent.
Much appreciated to have your opinions.
