Well, yes. I do want to play my job. I play almost every day and I love it.
One reason why many of us don't have achievements is that we primarily play the game on PartnerNet during development (Microsoft's test network), so we don't have achievements on Retail. But you can bet I'll be playing the crap out of Blitz when it arrives on my Xbox at home.
I play games I have made, sometimes I may take a break for a week or so after finishing the game, but if it's fun you play it. That's why we make games.
