So many? No...this is only occasional. There are quite a number of games that are only free for a certain time (like magic the gathering 2014 right now). Or where there's a catch (in magic, this is an obvious one. It's pretty much F2P but you'll pay for any virtual booster packs with cards).Gee, I can't believe I didn't know this. I thought it was only playable within the hours it was free. So many games I missed
Of course, there is a catch here as well: if you play and like this game, you're more inclined to buy sniper elite v3 (which is on sale right now ).
