Well, I'm still progressing on The Crew 2, The Crew Motorsport and Test Drive Unlimited Solar Crown.
Endless content still to keep me occupied in TC2 and TCM.
I was happy to only have 12 events left on the map not completed in TC2 (2 of those are acrobatics rubbish I can't do) and thinking I've then done everything finally after 7 months+ of regular playing.
Well, apart from the skills, photo ops, taxi events (season 4) and the stories, most of which are not yet completed... this game is infinite

If I ever get to the end, I'll start rerunning all the events in Hard mode. Which should last me another 7 months
TCM is proving to be just as infinite. I've now completed 11 playlists and a couple of Legacy Main Stages, plus all the challenges I can do on 3 of the playlists.
And maybe 50 Custom Mode races. But then there's 1000+ of those to do...
TDUSC - I have reached level 31, 61% of the map unlocked. Still running round car parks picking up rewards

I have now found all the rewards in 2 areas. Unlocked supercars at level 30, but have read that the best supercar is the Aventador SVJ which doesn't unlock until level 40 so I am saving my pennies to buy that when I get there. Still a lot of stuff left to do on this game too.
The only thing that's not progressing very quickly so far is Clan levels, I am still only on Streets level 12.
