First off ... If you were hankering for a quality Thomas's Cinnamon & Raisen Bagel, why would you go out and buy generic Shoprite english muffin, and try to smoosh raisens, and apply your own powdered cinnamon ... You get what you pay for ... You pay for what you get !
If Trainz is an official product of N2V, why wouldn't you buy direct from the N3V store Sim Central ? Why whould you purposely sidestep the official vrsion, and instead go out and buy a knock off version, from another store (the exception being Jointed Rail, which also sells the official N3V Trainz + a $20.00 Payware Gift from buying from their store).
