Yep that's about it. I would say for anyone who doesn't have TRS22 to go with Platinum, but if you have regular TRS22 not sure if it's really worth it. I'd consider myself a casual Trainz user...and even then I bought the PLL before TRS22 Platinum came out...so I got all of its worth a few months before it came out. Ah whatever. I upgraded, I'll probably stay on TRS22 Platinum for the next few years till TRS25 (or whatever the next version is) Platinum comes out
