I never have been able to figure out any of the games in these pre-orders :p There are some guesses down below if you go to the page. Galebourn (no idea who that is, just someone who posted there) says the following:
I'd say Sid Meier's Pirates, Colonization, Covert Action and a few other games like Dragonsphere will most likely be in this bundle.
Bundlestars had a "Pioneer's bundle" a few days ago. I'm pretty sure this will be almost the same, probably with 1 or 2 different games.
it contained the following games: Sid Meier's Colonization (Classic) / Sid Meier's Covert Action (Classic) / Sid Meier's Pirates! Gold Plus (Classic) / B-17 Flying Fortress: The Mighty 8th / Silent Service / Dragonsphere / Command H.Q. / Across The Rhine /
I also mention of Darklands, Redline, Gothic 1, and Jade Empire.
So really, I have no idea! It could be none of these! *throws hands in air*
