For you RTS lovers, Empire Earth series (except EE3, that game sucked).
Tell me more about AoE III! I have been eye balling this game for a while and might pick it up while it is on sale.
Risk.
Get off the keyboard, grab some friends and watch everyone not be able to hold on to Asia.
Europa Universalis IV is at a 70% discount on steam right now. I'm very tempted to pick it up for 9 bucks, but there's also a bundle with what looks like all the DLC for $25. Does anyone who's played it recommend getting the entire collection?
Get the whole collection - though the expansions aren't necessary to have a functional experience (not like CiV expansions!), they add enough things that you'll probably miss otherwise. And you're definitely not going to beat the price it's running for right now.
While you're at it, grab Victoria II...$6 right now and well worth it!
