Also, considering that the game is older, there are guides on how to run it on modern Windows versions. The setup.exe might need to be configured for compatibility, or a patched version of the installer might exist to avoid compatibility issues.
Moreover, if there's a community around modding the game, they might have developed a setup.exe that allows users to apply mods automatically during installation or configure the game to their preferences. Alternatively, there might be tools that modify the setup process for the game, adding features like anti-aliasing, resolution scaling, or other enhancements.
I should also consider potential technical aspects. For example, the original setup might require certain dependencies or drivers that some users might not have installed, leading to issues. A "better" setup could automate installing those prerequisites, check system compatibility, or offer a more user-friendly setup experience. Alternatively, maybe there's a setup.exe that allows for a custom installation path or better configuration of launch options.
