If you play modern PC games on a CRT monitor, @rootcompute runs a Steam Curator group called 'Does It 4:3?' (I'm a member!) with reviews and information regarding how well newer games support 4:3 resolutions.
Check it out and join up: https://store.steampowered.com/curator/43078746-Does-it-4-3
Also, there's a submission form for guest reviews to help contribute here: https://app.formly.so/f/urPmfA
