Mostly no. The distribution itself does not decide which games you can play.
Zorin OS should be perfectly capable of gaming. Zorin OS 18 is based on Ubuntu 24.04, and its software store supports software from the Zorin and Ubuntu repositories, Flathub and the Snap Store. Zorin also has official instructions for installing Steam, enabling Steam Play/Proton, and using Lutris and Heroic Games Launcher.
I personally game on Ubuntu Server 26.04 with KDE Plasma and X11. I started with a minimal server installation and only installed the desktop, gaming software and other components I actually needed.
That is not necessary for normal users, but it demonstrates that you do not need a special “gaming distribution” to play games on Linux.
I often explain a Linux distribution as being similar to a pre-built package or kit. It contains the Linux kernel, package manager, desktop environment, drivers, default programs and configuration that its developers believe most users will need.
It is technically much more than a ZIP file, but the comparison helps explain the basic idea.
Different distributions mostly give you:
- Different software installed by default
- Different desktop environments
- Different package managers
- Different update schedules
- Different default settings
- Different graphical tools
- Different levels of technical support
This means a gaming distribution may come with Steam, Wine, Lutris, MangoHud, GameMode, controller support and gaming-related fixes already installed or easily available.
A general-purpose distribution may require you to install some of those things yourself.
However, after the same gaming tools and correct drivers are installed, the actual games normally do not care whether the computer says Zorin, Ubuntu, Mint, Fedora, Arch or another mainstream distribution.
Steam uses Proton to run many Windows games on Linux. Proton is essentially a modified Wine environment together with components such as DXVK that translate Windows graphics APIs to Vulkan.
Lutris can manage games from Steam, GOG, Humble Bundle and many older platforms by combining Wine, emulators and compatibility layers.
Heroic provides access to Epic Games, GOG and Amazon libraries and is available as Flatpak, AppImage and several distribution-specific packages.
Flatpak applications are designed to work across many different Linux distributions because they use their own runtimes and can bundle the libraries they need.
Therefore, your son should generally have access to the same Steam, Lutris, Heroic, GOG and Epic games on Zorin as users of other mainstream distributions.
The biggest limitations are normally not the distribution. They are:
- The laptop’s CPU, GPU and amount of RAM
- Whether the correct graphics drivers are installed
- Whether the game works through Proton or Wine
- Whether the game uses an unsupported anti-cheat system
- Whether the developer has deliberately blocked Linux
- Whether the laptop supports Vulkan
Anti-cheat is an important example. Proton supports Easy Anti-Cheat and BattlEye, but support must often be enabled by the game developer. If the developer does not enable Linux support, changing from Zorin to another distribution normally will not fix it.
Distribution choice can still affect convenience and occasionally performance or compatibility.
A rolling distribution may receive newer kernels, Mesa versions and drivers more quickly. That can help very new hardware or games, but frequent large updates can also introduce new bugs.
Zorin and Ubuntu-based distributions normally focus more on stability and ease of use. That is often a better choice for a child, beginner or family computer where you want the machine to work without constantly maintaining it.
Valve officially supports the Steam Linux client on the latest Ubuntu LTS with common desktops such as GNOME and KDE. Since Zorin is based on Ubuntu, it is generally a sensible and beginner-friendly base for Steam gaming.
So my answer is:
Yes, you can install Zorin on your son’s laptop and still play the games that work on Linux through Steam, Proton, Lutris or Heroic.
A so-called gaming distribution may save you some setup work, but it does not unlock a separate secret library of Linux games.
The hardware, graphics drivers, Proton compatibility and anti-cheat support matter much more than the distribution’s name.
