My greatest games

This was a tricky list to compile. The top half contains the true greats, and the bottom half is the runners up. I'm mindful of the fact that several games that I haven't played could well merit inclusion (e.g. System Shock Remake, Majora's Mask, Metal Gear Solid, S.T.A.L.K.E.R.) but I'm restricting myself to games that I have played.

Two things ought to be mentioned regarding The Lost Vikings: firstly, that the Mega Drive/Genesis version contains five more levels than all the other ports, and secondly, that several good tribute games have been created, e.g. The Lost Kids, The Lost Snowmen, and The Lost Robos. And I'd like to add that No One Lives Forever (1) has the funniest dialogue I've ever heard in a game.
