I was just thinking about this now. Cyberpunk, for example, is a very good game, but it gets even better using the flying cars mod and realistic graphics.
GTA V is a very good game, but it gets even better on FiveM and with the favelas.
The Sims is good, but it’s nothing without mods and expansions.
CS 1.6 is also nothing without mods.
And you? Which game came to your mind?
