I’m about to start a forum for my games that Ive created, and I’m kind of stuck between choosing which forum solution to go with, so I thought i’d post here and ask if anyone has any input 
So basically I need something that will tie in nicely with an existing user base, would be nice if I could customise the login script to authenticate through a different system for example.
Should be simple to show generated character avatars under every body’s name when they post, show their in game names, etc.
I was looking at XenForo, looked at vBulletin 4/5 but to be honest I wasnt very impressed with it (full of bugs!), and I also took a look at IPB.
I’d prefer to go with a paid solution (money isnt really an issue) but if there’s a free one that can do all the above (and looks nice) that would be great too!
Something that utilises a lot of ajax to save page reloads would also be a big plus.
And as a forum user, which solution would you prefer?
