The Mod Couple x 10: 20 Unmissable Mods

For the last month, UserCreated have been presenting a series of short essays about their 20 (count 'em!) unmissable mods. It leans towards the last decade, but bar one ludicrous failure of judgment, it's a credible look at the entire width of possibilities inherent in mods, both in the hyper-popular and the artcore. Go see what you think. And, rather than just shouting THEY'VE MISSED ACTION-FACE-BIFF-VIII!, why not lob up your own short list of unmissable mods in the comments? 20 would be overkill, I suspect, but I'd be interested to read what your own selection of essential mods would be.
