I tried their Monaco track. Need to work out a bespoke setting because I want a bit more turn in on the McLaren. Will have to work on that.
I've had to take the following strategy, some of which you can do in F1 too - take a slap on the wrist for cutting inside Saint Devote at the start since I always end up in the back quarter of the grid; try and pass as you go up Beau Rivage to Massanet; squeeze through at Casino down to Mirabeau; turn in sharply through the Hotel Hairpin to gain position and then make sure you nail Portier to have a good run down through the tunnel to the Nouvelle Chicane (unlike F1 you cannot take the kink in the tunnel flat; you'll need to lift or tweak the shit out of your downforce settings. Which given the circuit isn't a bad idea). Lift through Tabac - again, unlike F1, can't go flat) and position for an inside overtake prior to Piscine. Last overtake is on La Rascasse and Anthony Noghes and you should be in P1 or P2.
I'm not really into car racing as much as people here, but I love and hate the game at the same time. When Smithy said it was a missed opportunity I didn't really understand -- people seemed really happy. But now I got more chance to play it... there are some annoyances. Career mode would have been better with better AI.
Having said that I think it's certainly worth buying both pCars and AC, if you are on PC. It's a shame that PC version of pCars cannot be modded like AC, as that might have brought us perfect budget simulator with good racing experience for PC.
