Saw someone's post today about their Half-Life collection, and i wanted to share mine too, so here it is. In case you're wondering why so many games are uninstalled, it's because i have to uninstall some games to be able to play others due to disk space. And yes, i do plan on buying Half-Life: Alyx in the future. Plus, since it requires a VR headset, something very expensive, not many people are going to own one, which drives me to think that HL:A isn't really a necessary addition in collection show-offs like this one.
Synergy is great with friends, just make sure to set the Half Life 2 beta to the build before the 20th anniversary so the textures dont appear as a flashbang white.
