A lot of you probably already know about this, but regardless...This is the kind of thing I like to see in mods:
I just found out about a Source mod-in-the-making, Orion, that is supposedly nearing its moment of release(meaning it will be released in 2007...). It has been in development for 7 years(they started on Goldsrc, then switched to Source when it was available). From the looks of things, it is a Halo-esque style game(some of you might even say they ripped Halo off), but with a lot more variety.
This game look absofuckinglutely breathtaking, and the gameplay sounds seriously awesome.
The Mod DB profile promises:
-Over 25 weapons
-4 Drivable Vehicles (with usable turrets)
-5 large-scaled maps
-Interactive Game-Mode - ViTAL
-Class-based Game-play
-3 positions - stand / crouch / prone
-Iron Sight / Advanced Scopes
-Weapon fire modes
-Melee Attacks
-Radio Commands
-Spectator Mode
-Upgrade system allowing for increased abilities.
And that's just for the first beta.
