Compared to the number of console gamers, PC games are a very small segment of the market. This is why I posted those comments. I don't want PC games to go away, and if they are growing then WONDERFUL!!!
I use to be an avid PC gamer, then I got married....
The keyboard mouse combination allows for more complexity of controls than a game controller could ever do. And some games like World of Warcraft (The crack cocaine of video games) could never be played on a console.
And yes a tablet will never be able to play these types of games. They have come a long way, but a PC will have much more power to it.
