Been addicted since Forza 3, not so much to 5 which I didn't enjoy, but with 6 I got it yesterday and as always the first thing I done was turn off all the assists etc. I set the drivatar difficulty to expert (I think?) and hammered the AI every time. So I will up that a bit more, but it leads me onto my main gripe I have sort of had since Forza 4 in that everything seems to be too "easy" and absolutely by now is handed to you on a plate.... I don't mean the ease of beating the AI, I mean the ease of getting cars and credits.
I remember in Forza 3 there were times I was desperate for a car, or to upgrade something on my current favourite car and I would have to go in and actively do a few of the race events purely to save up enough credits to buy some upgrades. I remember the really expensive 500k credit cars and what have you appearing to be almost an impossibility to get without putting hours and hours in and saving up..... With Forza 6, I am driver level 6 or something now and already have near a million credits and about 20 cars in my garage, 15 of which are useless and I will sell for some more money.
