In my opinion this is one helluva bundle.
I can personally recommend Van Helsing for those PC gamers who are into ARPGs and Galactic Civilizations II for those who are into strategy games.
In the BTA tier Terraria has a lot of fans. I've been wanting King of Fighters for a while and again Crusader Kings II is another very solid strategy game for those with time on their hands.
I already have the Age of Empires bundle and obviously those are classics that have been remastered for modern PC's.
