WHICH IS THE OLDEST GAME YOU'RE STILL PLAYING TODAY :)

I still can't get over the fact that Half-Life 2 came out like 17 years ago, so I am replaying Half-Life 2 lately, but with a bunch of mods to make it feel like a modern game. There are mods out there that bring the assets from Alyx into the game, along with modified versions of CM13 that remove all the lore-breaking graffiti, characters, and other questionable things from the mod. All the other mods combined with all the Half-Life 2 episodes take up about 63 GB, so it is a major upgrade. This combined with Reshade RTGI makes it basically next-gen.
