One of the benefits of PC gaming is the ability to use mods that can enrich the overall experience in certain games.
Skyrim, for example, has tens of thousands of mods created for it. One of the more popular ones is Enderal: Forgotten Stories, which overhauls the skills systems and gameplay mechanics.
GTA 5 is another heavily modded game with visual improvements and role playing servers.
