I have read in here since quite a while. I knew what AC was due to all the detailed info posted by the pc guys. I decided first to skip it because of Peugeot not being in and it being mainly for hotlapping.
The positive feedback on the feel of driving and the price here in France made me buy the game. However I didn't have very high expectations but was excited to test it out. I can surely see where all the complaints are coming from and I can even understand people being disappointed by the product. I have my list of issues as well but overall I enjoy this more than pCARS for example even if the latter is much richer on content, has weather and better graphics. AC does something to me that pCARS failed to do and I can not explain exactly what it is.
Beside the points allready mentioned by others, I am not an online racer so the multiplayer I don't care for. This to me feels a lot like the first TOCA on PSX. It was graphically not the most impressive, I didn't had much content, it was hard but I liked it. The same is for AC, I simply like it and I like it a lot. Many cars I don't care for in this game but the Alfa 155 is my little pearl with the Abarth 500 Cup Car as a decent second.
With the challenges and the career I wait until it gets more balanced. You have to search yourself which races are fun to do. I needs a bit of exploring and testing. Currently I am a very happy customer.
