I agree with Chris on some of his criticisms - the great graphics are often nullified by the heavy use of older assets in layouts (I plead guilty here). I suspect that this will be a negative for some time until all available content is brought up to TRS19, or at least TANE standard with the use of LODs and the elimination of all low resolution assets. The only alternative would have been to make a complete break with anything pre TANE - and if you thought that the complaints about having a subscription option for those who wanted it were bad enough, this alternative would have started wildfires.
Truly, the over-reliance on assets from TS2010 and earlier is TRS2019's biggest downfall. That much is obvious. However, i will hold off on criticizing TRS2019's content selection until the full game is released.
That's the problem with judging a beta version of a game. It's incomplete, and many of its issues will be (or at least, should be) solved throughout the beta-testing period.
