I agree with Gary here, this is a complete mistake. All the WoD games are way too different for them to be grouped together, specially old and new WoD, and this applies to w40k and all others. If you want to alleviate this problem with people not seeing any games, how about you make a second sub category. So let's say I select WoD in the main category, none in the second one, I'll see everything that's WoD. If I select WoD then let's say Vampire: The Masquerade, then I'll see the VtM games only. Same example with w40k, let's say I pick w40k then Dark Heresy as the subtype. As it is now, it will confuse people, frustrate them and will make it more difficult to find what they're looking for. There's no point in people having to click every single campaign to check what the campaign is actually about.
