I found a rather interesting chart on the
TRS19 faqs page. It shows that at the last Platinum Edition release the retail and subscription versions were feature identical.
Goal posts have been demonstratively moved.
At the time that the TRS19 Platinum Edition was released, the newest TrainzPlus update was the Content Store. The Content Store was made available, after a period of early access to TrainzPlus members, so as to allow us to greatly upgrade and improve the DLC system.
The following TrainzPlus update (trainzPlus update 4) added new effect layer tools, and the ability for effect layer presets, and this was a TrainzPlus exclusive until TRS22 was released. The next update, TrainzPlus update 5, added the initial version of Multiplayer Surveyor, and initial support for the TCCP2.0 system (this was then added to a TRS19 update).
TrainzPlus update 6 provided further MPS upgrades, in particular we made updates to allow us to add further content to MPS.
TrainzPlus update 7 introduced the first version of the water effect layer system.
TrainzPlus update 8 was the initial Surveyor 2.0 release.
TrainzPlus update 9 was alongside TRS22, and focused on further MPS updates.
As noted multiple times, TrainzPlus users gain early access to new features. These new features are intended for future retail releases, and are often fine tuned between their TrainzPlus release and retail release. If a particular retail release doesn't include features that interest you, then that is fine, we fully understand that not every release will interest everyone. This is also why we offer versions such as the TRS22 Platinum Edition, which add new features and content over the TRS22 standard edition, as this may interest those who otherwise weren't interested in the TRS22 standard edition.
However as has been the case since TrainzPlus was first released, the TrainzPlus versions will include new features before they become readily available. In some cases, features may change before final retail release based upon feedback received from TrainzPlus members, or based upon further development in Trainz.
In the case of MPS, the retail version is limited to a select few routes and has been advertised as such since TRS22 was announced. This is in part as we have continued development of the MPS system itself since then, as well as to monitor the data requirements for the MPS system in general.
