Now that's some bullshit.
Liam from the Super Best Friends has lambasted mobile often on their podcast, and has gone on record as saying the format isn't just a negative section of the market but is KILLING GAMES. I've sometimes felt like he's responding more emotionally than with any real basis, but stuff like this really makes you wonder.
I seriously hope there is a movement away from mobile in the near future though. It just seems stagnant.
