Just throwing that out there... but look they have the army system (I am working for a vbulletin version currently.), they have a working casino system... and alot of other "little things" that vbulletin is lacking.
A link to IPB's full releases for the version before the most recent (because the most recent doesn't have much out yet.):

This is a link to 2.1 invision modification's root:

I seriously don't mean to seem like I am promoting IPB I don't even own the software, it just appears that Vbulletin is beginning to lose it's edge in the hacking community. Again... I am not a contributing coder to vb.org so I have no right to complain, I am just throwing this out there for discussion.
