ME3 has more than 500+ tags at the moment, and we are starting to get a number of duplicates (including ones I've opened). Should we consider going through old questions to add more tags to them to be more specific so that people searching can better find matches and reduce duplicates?
Adding cross-game tags like weapons is not a good idea. It confuses things, and really, how many people are going to be interested specifically in ME3 questions relating to weapons specifically (and want to filter based on that)? The only extra tags that should need to be added for most questions is platform tags, where appropriate.
Sure, the homepage is a mass-effect-3 party at the moment, but so it was for Skyrim, for Starcraft 2, for Minecraft etc. etc. That's just the nature of the game!
The only "bonus" tags that I think are worthwhile are the ones we've already been using:
- ps3 xbox-360 and pc when a question is specific to a certain platform
- multiplayer when talking about the game's multiplayer component
Tags are best when they provide necessary context for the question. If the context isn't needed (such as weapons), it just becomes noise.
There may be some secondary tags that could be of use, for example missions-citadel, missions-priority in the style and intent of tags like zerg but I would be reluctant to see whole scale secondary tagging.
Good titles are better than bad tags ... makes the answer easier to find in search or google anyways, imo.
