I guess I don't game much, but yes that can be added too. Still there is a huge gap between phone games and PC and console games.

There definitely is a gap but not in the way I think you meant; in case you were not aware, mobile games are now the biggest market segment of video games period (console, PC included)

Considering you missed the #1 market, maybe your research techniques might be lacking?

Also, for clarity, the browsing and gaming done on phones isn't casual.
