It's a licensing restriction, no doubt, but the track is such a rarity in games, I still welcome its inclusion.
Now, is anyone interested to talk about one single piece of new content from the DLC (or even not from the DLC would be fine)?
Seriously, after the Fun Pack, Ferrari was my least anticipated DLC, but it surprisingly ended up being my favorite of all, largely because the included cars are some of the best to drive in the entire game, (250 GTB & 355 Challenge being my personal favs). Mugello is too often overlooked and makes for a wonderful addition to the track roster, especially with PC2's weather and TOD options.
What I most look forward to when a SMS DLC comes out, though, is the "Physics of..." posts by their vehicle lead, Casey Ringley, and he's genuinely outdone himself with his writeups on the Ferrari pack. There's some fascinating stuff in there.
