Enamored of the Free that Isn't

I find my game time dominated by a small portion of free-to-play (aka freemium, f2p) games that have all, surprisingly, earned money from me. No, I'm not talking about games on Facebook or even iPhone apps. These are huge games on the PC!

I still think the majority of Facebook and iPhone free-to-play games need to do more to entice me, both as a player and a payer. But, if World of Tanks and Spiral Knights are indicative of the future, I'm all for it.
