I love Grid Autosport, & although pitstops may have been good for the title overall, what makes the endurance mode so good is the fact that you cannot change your tires, you have to drive accordingly & manage the grip loss throughout the race. If you could just come in & change tires it wouldn't be an good as it is. I personally just go flat out from the off, try to build a gap & deal with the consequences later on. As for the AI, I know there is a lot of opinion about it but personally I think it's some of the best out there. Yes I know their aggressive but I love it, it's an intense experience until the chequered flag.
