The analogy I use is that 'World of Warcraft' is like going to the mall: you see a ton of people there, but you don't really want to interact with them; you just want to know you're part of the human race. And if you get in trouble, you'll know someone else is there.

I think DOOM had just the right mix of elements that keep people coming back to it: great monsters, excellent weapons with great balance, a spooky environment and extreme speed.

I completely love playing and designing games and always will. I am so into games that I listen to game music all day. That may sound strange, but you can guarantee I'm a hardcore gamer and would never let you down by designing a crappy title.

You have to design and program differently. Combat action in an MMO is so different to combat in a first-person shooter.

What I didn't foresee in 2005 was the rise of the post-PC, which are all these tablets now. These are the things that actually will probably be the end of the consoles.
