PC Gamer: If you could play a sequel to any game, what would it be?

PC gamer’s staff have interesting choices.  http://www.pcgamer.com/if-you-could-have-a-sequel-to-any-game-what-would-it-be/

Since I have been playing MMOs almost exclusively this year, and perhaps most years,  I haven’t any new game choices.    I was unable to pick just one, though Realms of the Haunting tops the list.  Why, why, why, that ending?   After all we’d been through?  (sniff)

Realms of the Haunting

System Shock (3)

Skyrim

Neverwinter Nights

Half Life
