Well I had requested a game cms a few months back, but with not much feedback.
I have a license to vgportal, but that is seriously bugged and not supported.
I then found a new game cms which had come onto the market called customcms which now makes gaming cms, sports cms, and a few others i think.
This was originally a complete package which contains its own forums, and other things. however because I needed it integrated into vbulletin, it has taken me a little while to get the most out of it, but it is getting there.
if you want to see it in use, it is
www.gamerzneeds.net however once I have finished upgrading it next week, and doing a few other things to it, I will then be getting a custom design made for it as well.
There is a market out there for a gaming cms that is fully integrated into vbulletin, which can have its skins integrated into vbulletin, and also have all the features of a really good cms.
If you were to do this successfully, and have an importer to import my data from my current cms, I would switch over no questions asked.
Thanks.
