I agree that Opposing force has so many weapons that quite a few of them don’t get much time to shine. And a lot of them come in the last third of the game. Would have loved more chances to use the sniper and the squid gun.

I think blue shift is my favorite just due to the story but I do have to agree that none of the expansions can compete with the gameplay of the original.

Decay is its own thing. I’ve quite enjoyed almost more as an arcade experience where you can compete for the high score and get some more half life lore than it being its own stand alone thing.

Solid perspective, thanks for sharing
