For me, it would be about 18 or so hours. A bunch of years back, I decided to play through an full 24 hour race in the Sega Dreamcast game Test Drive Le Mans and ended up staying up for about 18 hours straight racing in real time, taking breaks every two hours or so just like drivers would in the actual event. I didn’t have a co-driver, so it was all me going for it against that pack through a rather busy race day that started off nice and sunny before growing darker and cloudier as a storm rolled through about a third of the way in. Anyway, it looks as if GRID Autosport is going to go a longer way in reminding me those days of staying up so long might be over to some extent thanks to more realism and what’s looking like some harder courses to tackle. As I noted last week, I like challenging myself with a racing game like this where one’s knowledge of the courses increases as stamina decreases. Just when you’ve hot that stride and the miles fly by, you feel the need for a nap coming on or you have to pee or your stomach starts growling louder than the engine of the car you’re driving. Yeah, good times… until you yawn or sneeze and wreck yourself right out of that race. In other words, I can’t wait for this game to ship!
