Hey guys, I have not been to DL to play Infinity in a while, but I have played N3 with a private group several times now. The rules are a lot more tight and less open to silly interpretation than before, and I generally enjoy it a lot more than N2. Most of the open questions about the rules are around the Human Sphere and Paradiso stuff. They have published profiles and a FAQ but not official rules for it yet. It's definitely playable just not quite as water tight as the core rules.

Things to watch out for that are super different: mostly suppressive fire which is completely changed and we misplayed about a zillion times. Only certain weapons can do it (sometimes only certain modes of certain weapons), the range bands totally change, it's always B3 (but ammo type and damage are as per weapon used), and it is -3 to face anyone in supp fire (i.e. -3 to the other person being suppressed). Oh yeah and it uses your full LoF not just a corridor anymore. I think we managed to forget at least one of those things every time so far. It also makes things like Total Reaction and Neurocinetics interesting, since those give you full burst in ARO at full range so are better than supp fire in many ways.

CC is not that much different, they buffed several CC troops, there is Surprise Attack when charging out of camp or Impersonation, Marital Arts is way different, and in general when a token executes an order that reveals it, it counts as revealed the whole order so people can shoot a camo token on the charge.
