I just noticed this question and saw the nfs2se tag, so I went to see what it was, because from that tag name, it is not obvious what game is being talked about at all. The question itself had to explain what the tag stood for, but I don't think a question using a tag should have to do that.
Since it would actually fit in under 25 characters, I think need-for-speed-2-se would make more sense and look a lot better than nfs2se.
However, this tag already has a tag wiki written for it and I'd hate to erase the work put into that by just editing that question to have the new tag. Would it be possible to transfer the tag wiki to a new need-for-speed-2-se tag via a tag rename? The existing nfs2se could even be a synonym of this tag if people wanted that; I just don't think it's necessary to abbreviate the base tag to that degree.
