@blumlaut AC can be genuine fun. Just a lot of it is mods. I had some great fun there as well. Though I guess if you are more into GT-stuff ACC is obvs. the better choice. Or longer stuff as well as Endurance on AC is a pain.
(Also I dunno how much more work it is to run the server as well)
I am just not into like Big GT-cars like GT3. GT4 and GT5 maybe but I really live for the TCRs and the Cup Cars and the like. A little slower but close racing that also can be a tad scuffy here and there.
