openjazz VS HeroicGamesLauncher

For proof you can read this github issue where one of the top contributors mentions that OpenJazz has no saving, since they want saves to be compatible with the original game, but the save format is encoded and needs to be reverse engineered first (means that they don't have the source of the original)

OpenJazz - Open source reimplementation project for Jazz Jackrabbit 1.

There's openjazz at least, if not an official port.

Heroic Games Launcher: Support is limited to Epic, GOG and Amazon but the advantage is that it can manage their games itself without the need of their own launchers. Doesn't have support for tags currently.

For "normal" games you could look yourself using ProtonDB regarding every game released on Steam and AreWeAntiCheatYet for most multiplayer games. If a game isn't available on Steam you have three possibilities. First if it's available on GOG, Epic Games or Amazon Gaming, you could use the Heroic Games Launcher. Second you could try to run the launchers through Steam itself using once again Proton. Third you could try installing it with a script or tutorial in Lutris or Bottles.

Maybe also look into HeroicGamesLauncher and how to install it, Steam isn't the only platform for gaming and HeroicGamesLauncher help with the following platform: GoG (Good Old Games) and EGS (Epic Game Store).
