I have a T450, I’m dual booting Windows 10 and Ubuntu (…I know, I know, I’m just too lazy to swap) on it and it works great, I get better performance on Ubuntu than I do on Windows. The fans worked oob.

Nothing quite like Hardspace: Shipbreaker, but farming games/life sims often fill this niche for me. The classic one to recommend is Stardew Valley, I also really like Graveyard Keeper, Slime Rancher and Fantasy Life (3ds, works well on emulators).

ARPGs (Diablo style, so kill stuff to get loot to get your numbers up to kill bigger stuff) can be nice zone out games too, I recommend Grim Dawn (going to get an expansion soon, quite complex), recently released Last Epoch (very enjoyable, but might want to hold off for a while if you want to play online - the servers are a mess right now), and Chronicon (most casual of these three, very cheap, colorful explosions across the screens).

Other games I’ve tagged as “Space Maintenance” : Planet Crafter (pretty chill number go up/building kind of game where you’re slowly making a planet livable), Deep Sixed (short roguelike, try to keep a ship together enough to get through the game, very hectic and no progression between runs so may not be what you’re looking for), Delta V Rings of Saturn (top down space mining).

Trams are, as you’ve noticed, a different usecase - subways are for getting you from A to B quickly, and trams are for getting you to the subway stop/straight to your destination on a shorter trip. One prioritises speed and throughput, the other - access and ease of use. Both should be used together to form a good transportation network, with buses and trains going to more remote/less dense areas.
