POL-POM-4 VS snapcraft

Should the website www.playonlinux.com indicate the situation more clearly too? Any clarification? What do you think of this "mess"?

I noticed the Call of Duty series on Steam, so I expect most or all of them will play perfectly fine on Linux Mint in Steam. If you want to play Windows games outside of Steam, there are apps like Lutris and PlayOnLinux that make running Windows games on Linux pretty easy. https://lutris.net/ https://www.playonlinux.com/ https://www.protondb.com/search?q=call%20of%20duty

If you will to run a game with Wine, use the release version. You can also use PlayOnLinux (I feel old mentioning this), Lutris, and Bottles (this new one I didn't tested yet).

So, I don't use WINE directly. Instead, I use PlayOnLinux, which hides most of the complexity for you. It handles all the WINE stuff on your behalf. It looks like you're using Ubuntu (please remember to include your Linux version in future!), so you can install PlayOnLinux from the standard repositories.

I believe POL is basically dead, see the repo here: https://github.com/PlayOnLinux/POL-POM-4/commits/master where there were only 10 commits over the last 2 years.

https://www.playonlinux.com/ is a good resource to get Windows Apps up and running easily and has a compatibility list of most software

There are also GUI front-ends for WINE. PlayOnLinux has been around for a long time, and Bottles has recently come on the scene. I don't know how to use WINE, but I can use it because of those two apps.

If you want to know if a game is playable or not and it doesn't have a linux version, then the best way I know of is looking it up on lutris. You can't look on protondb, because it's only for Steam games. You can also look on wine and playonlinux, but they usually aren't as exhaustive as lutris.

I find WINE quite complicated to use, so I use PlayOnLinux, which is a front-end for WINE. Unless you need expert mode, it's way easier to use PlayOnLinux than to have to fiddle with setting up an app directly with WINE.

Back in the day, I used snapd, which is similar to Mac's Homebrew.

Hopping from one distro to another with a different package manager might require some time to adapt. Using a package manager that can be installed on most distro is one way to help you get to work faster. Flatpak is one of them; other alternative are Snap, Nix or Homebrew. Flatpak is a good starter, and if you have a bunch of free time, I suggest trying Nix.

My personal favourite IDE for java is Intellej Idea. Apart from not demanding the extra extension, It was designed special for Java and Java related languages so it runs java smoothly with great compilation time. so lets install it. Make sure you have snap before installing it

Linux Mints App Store is full of GUI programs, Snap Store ist full of it, Flathub is full of it.

You are being lazy. But I recommend bringing your ass directly to snapcraft.io and reading those documents in the Learn section!!

https://github.com/snapcore/snapcraft - not sure, but looks like a building tools for snaps

Besides, there may be other ways to install them, although there doesn't seem no such Flatpak packages in Flathub. For example, some senerio to use some release channel or Docker / Podman. Additionally, when you use a different Linux distro where systemd is adopted and therefore can do Snaps (Snapd), you have another possibility.
