Only for Empires, so no I don't think it's steam's fault. and I know for a fact I'm not the only one with this bug.
Well, i just checked steam and appears to be the same situation. Ony a few people. Actually just two Bob and TheCreeper. Have like 20 other people who play empires least weekly. And on other games like PD the heist i have my entire friend list even people who have played it for less than a few hours.
