You should get into Paradox grand strategy games. They're hyper-addictive and go on massive sales like every 3 months. Hearts of Iron 2 and Europa Universalis 3 are their best works. Some people dig Victoria II although it's not for me, and Crusader Kings 2 is apparently solid but it's new so you should just wait for the price to plunge. It's not uncommon to be able to get a year-old Paradox game for five bucks in a sale.
