Ok, the title might seem a little stupid because I have no idea what this kind of thing is called. For example, when I click on team-fortress-2, I see in the related tags section:
Aren't these technically all related to Team Fortress 2? Unlike Minecraft, which has different versions of gameplay (e.g. Minecraft-smp, minecraft-Bukkit), these tags are all about TF2. I guess you could says at picking a different character is kind of like another version of gameplay, but to me, its really all the same.
So what's the scope on this?
