I've seen people get upset over less underhanded Monopoly grabs, but I wouldn't expect the bad feeling to linger excessively.

As an example, I made a legitimate trade request for a resource I knew an opponent had (it had been recently rolled), but was rejected.  I responded with the Monopoly card, even though it netted only one of the resource, because I really needed it that turn.  The other players were much more wary of my trade requests for the rest of the game; one even asked what would happen if they refused.

Is pretending to want to trade before playing a monopoly card objectionable?
The term Engine life factor going by the name suggests that higher the value more is the life of the engine. If so why doesn't companies specify this as a part of their standard specifications?
