Yeah they are and this also is. There is no such thing as "endless possibilities". At one point you are gonna run out of things to do, things that intrest you. Everyone will reach that point.
Driving and tuning virtual cars on one’s PC is either an interesting experience to one or it is not. It’s not going to become a more interesting experience if one starts getting pretend digital trophies or pretend money for every rally stage completed etc, on some kind of arbitrary ladders. Not unless one is the NPCiest of NPCs. If I were calling the shots I’d like to see the devs spending 85% of man-hours on improving force feedback communicativeness, physics, and “terrain interaction”, ie in certain situations grip dynamically changing as your tires change the terrain. New modes, better graphics even new cars and maps are second to those things.
RoR is still actually in kinda heavy development Though I think now, the devs are more focusing on making not quite a BeamNG alternative, but something else. There are dev builds available that are updated almost weekly. The main dev also announced on the Discord server that there could be a prototype vehicle creator where like in Screw Drivers, you connect blocks together and use some of the many planned GUIs to make a fully functioning vehicle. In the same announcement, he also said there could be an option to use individual beams and nodes for more advanced people And another thing, RoR is gonna move to a new graphics engine that would make pretty much everything look better without having to use things like ReShade. Just because RoR is a predecessor to BeamNG really doesn't mean it's completely dead at all.
The fact it's still being updated is very impressive considering its age, and I have a lot of respect for the RoR developers sticking with the game but it's a different game in its own right, and will never be a clear alternative to BeamNG
