Well wouldn't be my "best game" and I generally dislike racing games, and it's a particularly old one, actually, but I recently managed to get a huge session of random people except for one friend on Racedriver: GRID. We did many races and generally had a lot of fun spinning each other out and suffering terminal damage at the first corner, lol. On 24 Hours in Le Mans there's a massive straight, gives you easily enough time in the top car class (LMP1, Le Mans Prototype 1st class) which we all had anyway to hit 220mph easily...so when our group of like 10 cars smashed into the barrier without caring to turn as we just blammed down the straight..was hilarious. The guy who survived just immediately trashed his car to end the race and move onto the next one, lol. Fun fun, for such an old and somewhat inferior game.
