Steam was released today, finally nonbeta. my roommate has a copy of day of defeat retail, and we're trying to get counterstrike installed on his computer. however, steam will not let his DoD cd key be used to install CS, while the box for DoD says he should have everything he needs to play all half life mods.
we are reading on all of their forums right now, but does anyone know of a solution offhand? any help is appreciated, as i really really want to knife him on de_dust
