We had a day out among the whole Bugbear staff last week. It was to a place specializes in multiplayer racing games. Free beers for everyone too!
10 sets of G27's and 10 GT5's in local network. Was hella fun! I was, of course, the fastest.
There was also one of these things:
A Force Dynamics racing simulator! Raced a Formula 1 simulator in it and it would pitch and roll while accelerating, turning and braking based on the g-forces present in the game. It was pretty darn intense! I raced only 3 laps on Monza Autodromo and even after that my palms were aching. I can't imagine how the real formula drivers can do it for a couple of hours straight!
