I don't know that all of these need to die, perhaps some are deserving. They just all seemed a little weird.
gemcraft - We have tags for most of the games, maybe this should just die?
races - sort of ambiguously used and not very descriptive.
These are more just "what's the purpose of filtering questions this way?" kind of tags:
I pretty much expect these to live, given the current tag climate. They just don't seem terribly useful to me personally.
