The following tags were selected based on the criteria that they are too specific to provide a meaningful distinction amongst questions and should be killed or merged. I've done my best to find merge targets whenever I can.
Wiimotes are wireless controllers, and I don't know that having three categories that could potentially contain controller questions is really warranted.
LAN as a tag is kind of ambiguous, and I'm not sure there's enough of a meaningful distinction that someone interested in gaming on a LAN versus network gaming in general. I'm also kind of torn, since this could just as easily all become "multiplayer" - there are likely few networking questions valid for this site that don't involve multiplayer in some way...
Cheats is a meta tag, (which might die in a fire sooner or later) but regardless I'm not sure that the Konami code needs a tag all its own.
This is a weird group. Hosting generally refers to dedicated servers in the gaming world.
Two game mechanics of the CoD series. There's a bunch of questions about these mechanics that don't have them, and there's not really a need for them since the CoD game question count is pretty paltry.
