Of the games in the bundle I'd recommend most of them, the only titles I haven't really played are Crusader Kings II and The King of Fighters. Van Helsing offers up some great Diablo 2 style RPG action, and Deadlight has an interesting take on the zombie genre. Terraria is akin to a 2D Minecraft, but with way more crazy stuff going on.
