Whoa, I did not expect this, but I'm buying it sight unseen even at $50, because in my whole gaming life, there was only Half Life, C&C, and Halo that stood out (well, and Phantasmagoria, but that's a very different type and genre).
Plus I'm glad Paramount is doing this at all and we should support such physical media releases to show other studios it's worth it to release their streaming series exclusives on disc!
