Free-to-play games are everywhere these days, and everyone seems to be playing them. Dota 2, League of Legends, and World of Tanks are all pretty popular. I've heard a fair number of folks talking about Warframe and Hawken, too. And we can't forget Team Fortress 2, which like many other free-to-play releases, got its start as something you paid for.
Admittedly, my own time in the freemium world has been extremely limited. I logged a couple of hours in Warframe with a friend of mine a few weeks ago, but that's about it. The game was fun, though—certainly worth what it cost me.
What about you? Are you a free-loading gamer, and if so, which titles do you play? How much time do you spend with free-to-play titles versus traditional games? Bought any hats or other freemium content?
