Apart from drafting a card from the market that someone else has their eye on, is there any player interaction? Stealing resources or points? Manipulating their dice? I've glanced through quickly and I don't see much.
No. If you are looking for high player interaction this is probably not your game. You do have to keep an eye on what the other players are doing and consider "hate" drafting from time to time. There are cards that cascade off each other rather well and you may not want to let them fall into your opponents' hands.
