I'll be adding skins today. It currently has two RPG mods, 57 arcade games, and lord knows how many other features. I'll be adding costs for arcade games and prizes as time goes on.
if you mean the portal then i think there is a mod for it for phpbb. I use ipb so i don't know much about phpbb. Just google search "portal for phpbb" and see what comes up.
No, Invision, while I feel is the better generic board, doesn't allow premodded packages like this. There are individual mods that you could install to make a board, but it would take some time, and there aren't nearly as many mods for Invision.
