I don't mean the orange box I mean everything, from number one to episode two and all the add ons too. This is on steam but I want physical disks. Is there one about?
If you're buying on PC, the Orange Box etc require you to update via Steam anyway, so it's a moot point.
Is there a single box-set for all games? Probably not. Can you buy them all separately? Yes, one way or another.
As far as Episode Two goes, it wasn't released on physical disks aside from the Orange Box, as a Steam-linked game. The disk would just end up as a fancy coaster. You can get Half-Life 2 Holiday Collection, which gives you HL2, Deathmatch, and Ep1 here for £11, but same rules would apply, I'd imagine - it's just install media, and Steam linked.
Half Life Generations contains H-L the 2 expansion packs and Counterstrike (stand alone games but you can register the keys with Steam to add them to your account.) Orange box contains HL2 / Ep.1/Ep.2/Team Fortress 2 (and requires steam anyway)
you could buy the valve complete pack, it gives you everything valve have ever made, evar, and it's usually very well discounted around christmas time. edit, nvm, i'm a retard who can't read.
