Sim City 4 is the best version of the Sim City games, and is 75% off on GOG right now, $5 / £4.
Cities Skylines 1 is the best modern city builder, 3D and a lot of fun plus well designed. But only really worth it when it’s on sale; lots of DLC and overpriced as a package when not on sale. Avoid Cities Skylines 2 - it’s just not fun and hasn’t been fixed - maybe they will one day fix but I doubt it 2.5 years in…




This laptop is more than capable of running SNES emulation; its 1GHz quadcore, and 4gb ram.
SNES is an old system which had 3.58Mhz CPU and 128kb ram; you’ll be able to emulate it without much issue on that laptop. BSNES has low requirements (like an Athlon or Pentium 4, and 512mb ram, and Open GL2), although if you have problems then Snes9x and ZSnes are less accurate but lighter weight. RetroArch is pretty convenient way to deploy emulators and has BSNES, Snes9x and Snex9x_Next cores to use.
A lightweight Desktop Environement may help make the laptop feel snappier; Xfce or Lxqt. If it feels slow then you want a minimal desktop which doesn’t have overhead like compositing. Also don’t use flatpaks especially if you multitask; use native apps as flatpaks have some overhead.
Mint as a distro is fine for installing lightweight desktop environments, and if you wanted you could install Linux Mint Xfce edition from scratch.
