No question that mobile games have come a long way in a short period of time, my "take away" is still that PC gaming is NOT dead, which was predicted and bemoaned by many gaming media sites and magazines specifically because of that mobile growth. The opposite has happened, PC gaming has gotten stronger. During the early to mid 2000s, even later, if you googled PC dying, you got the phone book for articles. It was true in some sense as well, all the data pointed that way.
Remember how many simulation games were made from 1997 to say 2002? Dozens every year. It dropped to a fraction of that after those glory years, and sales plummeted for those box game sims too. Even FPS games were falling in popularity/sales in that time period.
It's coming back strong now, AH3, DCS obviously, IL2, RoF, and many others are all alive and kicking still.
