1) TES4: Oblivion (no link required, I'd imagine)
2)
Dreamfall - The Longest Journey
3)
S.T.A.L.K.E.R. Shadow of Chernobyl (though god knows when it'll come out, its been delayed about as much as Duke Nukem Forever, now)
4)
Indigo Prophecy; aka Farenheit
5) Omikron 2 (Which should come after Farenheit at some point - sequel to one of the greatest games ever)
6)
Alan Wake
What's AN3, out of curiosity? And isn't Fallout going to be released sometime after Oblivion, seeing how Bethesda have taken up the license?
