The game is a great choice. I have a buddy that has one, and it’s both fun to play and great looking. If you’re a Trek fan, and who in their right mind is not, then this game will be great for you.
You will always pay more for a new game (and get less for a used game) when you buy from a “store” since they have to pay for rent, employees, inventory, etc. however, if it is a reliable business who will stand behind what they are selling That’s worth something. You won’t have to deal with the hassles of buying and selling from/to private parties. Kind of like trading in a car to a dealership: absolutely, you could do better on the deal, but is it worth the work?
