Plus there is no pile of money with NOLF.
If the gog wishlist is anything to go by, at least 10k+ people want to shell out a few bucks for it (25th in the list, 26th being NOLF: GOTYE). It's not Grim Fandango large, but it's still a fair pile of cash I'd bet. I mean No One Lives Forever literally only needs a new installer and proper widescreen support and it's set.
