I lol'd. How is it comparable, when iRacing costs about 33% more per month - oh and we're only talking about the subscription - add some content and you'll be way over 50% cost difference. Where with iGP you pay for your subscription and you get all the features available with no extra payments.
Also there was an offer to the F1 Season Start with 25% off on a one year subscription, which then ran at £30 - and that is £2.50 per month, how is that comparable to iRacing !? Since you missed that one, you might want to look out for the special offers in the future, though
Well anything is worth a buy including a PS3 + GT5
Laser scanned Nordschleife with relatively good physics on at least road cars (as long as you stay for road-hard and slick-hard and dont try softs as they get pretty unrealistic) and the enormous car choice, is a quite good reason to buy it
