I just did a minimal amount of googling and this is absolutely not true. Micro transactions have outpaced full game sales by almost 3:1. The entire model of free to play games relies on microtransactions. The biggest games in the world right now are f2p games or paid games with f2p models. I dunno where you're getting your info from, ancedotally, I'm sure, and maybe you just don't play games like that... But the rest of the casual game player population absolutely does.
