My personal analysis is that this excessive EULA is part of an overall strategy.
Some days before the TS2013 upgrade, I have posted this analysis to the steam forum :
http://forums.steampowered.com/forums/showthread.php?t=2941007This analysis has triggered some interesting comments and reactions.
This is now confirmed and a new TS2013 user who want to buy the old TS2012 assets and route perimeter will have to pay a big amount of money (and he will not get all the route).
There is also another point: More than half of the former DLC (e.g. GP9, SW1500, ...) have disappeared from Steam Catalogue.
If you have a look to some commercial third party offering this a big kill for their business (E.g. 75% of Footeforward product catalogue is not anymore accessible to new users since required DLC are not on sell - Almost the same thing for Train & Driver, Armstrong Powerhouse and so on).
So at the same time RSC has
- suppressed what we called the "core game" from the game thus jeopardizing many freeware and commercial products
- made part of this "old core" DLC payware which now install in different location so freeware and commercial products have to be re engineered (and become also more expensive for new users)
- suppressed more than half of the former DLC sold on Steam thus rendering many freeware and commercial products inaccessible for new users
- written down an hyper restrictive EULA
I am not an adept of conspiracy theories but these are now facts.
If I take a cynical stance, these moves are
- a mean to make additional money with the work of freeware and commercial add-ons (for new users)
- a mean to restrict (at best) third party commercial activity to a pool of selected developers/companies controlled by RSC through licence agreement to be negotiated
So I am not surprised that some have already thrown in the towel .
