I have Valdis Story but it won't run at all.

The fact there were so many MR members that expressed their happiness about the fact that Apple was dropping 32bit support still boggles my mind.....
I don't know if its good or bad, just that it does cut off a segment of apps/games that will no longer run

New guy here. I have steam on my 2015 mbp 13 and haven’t had any issues running games in Catalina. It does give me the warning but the games play anyway.

Some of them runs fine but may crash like in Dead Cells (I heard of it).
So it depends of which game you try to run.

Hello, a few days ago I ran (just to test performance), the CS GO on OS X Catalina with a Mac Mini, I don't know if the data is useful.

Is CS:GO a 64-bit game?
I can not confirm 100%, but I think that because of the age (+10 years) it has is a 32-bit game, it is more a legend that warns that maybe the game may not run, but still runs.

You can run 32-bit in an emulator, like Fusion or Parallels.

Was there something you needed from Catalina that Mojave didn't have (i.e. why did you decide to upgrade) ?

The easiest option would be to run the Windows version of the game under bootcamp.

Another solution might be to install a bootable version of the previous OS onto an external drive and to boot off of the external drive.

A more complicated option (depending on if you have a time machine backup before you upgraded) would be to either restore or reinstall the previous operating system (don't try this unless you know what you are doing).

CS:GO was created in 2012 (8 years old) and was updated to 64 bit in 2016.

Well I already downgraded to Mojava because I got sick of this and because Catalina is unstable.

Mojava is more stable.

What really sucks is that they've removed a lot of 32-bit games from Steam and the MAS, leaving users of older systems out of luck. Some of those games are now lost to time unless existing owners can crack them.

CrossOver 19 can run most dx9 32bit Windows games directly in Catalina and they often run better than original Mac ports.
It has free trial

Is suppose these games were not coded in 32 bits or that this was not under catalina, because there is no way to run a 32-bit app in catalina without some sort of emulation.

The Steam warnings were generated en-masse so it's not at all clear from them whether the game is in fact compatible. Sometimes the system requirements can give you a clue: for example a game said it required a 64-bit processor and operating system; and that worked fine (despite the warning). Otherwise you can ask in the forums. It's best to have confirmation before buying anything.

Of course, many older games aren't compatible and simply won't ever be updated to 64-bit. It doesn't bother me because Bootcamp always was (and remains) the best solution for gaming on a Mac. I'm happy for macOS to be "cutting edge" and for Windows to keep long-running compatibility.
