HeroicBashLauncher VS HeroicGamesLauncher

Can you utilize addtosteam.sh with this similar to how heroic did?

I've previously used Heroic Bash Launcher for that. It generates a script that opens the game in exactly the same way Heroic does, and you can then add the script as a non steam game.

The EUREKA moment came from a thread for CIV IV on a random Heroic Launcher Github thread. https://github.com/redromnon/HeroicBashLauncher/issues/38

Works for me with Lutris shortcuts and some native Linux games I have installed. Herioc shortcuts needs an extra step using Heroic Bash Launcher

You're probably better launching through heroic and not directly using proton. This project looks like it might add all your heroic games to steam automatically: https://github.com/redromnon/HeroicBashLauncher

Heroic Bash Launcher

Use Heroic Launcher (find in desktop mode via discover (flatpack)). Install Windows versions to take advantage of Steam/Proton. Sync saves using Heroic Launcher too (be careful the feature is currently in Beta, but working fine for me in D:OS). Install the shortcut in your steam library using Heroic Bash Launcher, job done.

For heroic installed games, i used https://github.com/redromnon/HeroicBashLauncher to add steam shortcuts for individual games.

But for Heroic, afaik you need this, though I am still working on the guide and can't 100% confirm.

More likely things like https://heroicgameslauncher.com/

try heroic

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).
