To me, this isn't a list of "best games" but rather a list of "classic games".
That probably sums it up best, and if that's the case, then you can make good arguments for most of those games being on it.
I can't remember a more highly-regarded game than Myst. Everyone spoke well of it, not just gamers. Many first-time computer buyers at the time made Myst their first software purchase, because it was regarded as intelligent software that took excellent advantage of state-of-the-art graphics capabilities.
Civilization is the Monopoly of computer games. It's the single best idea anyone's thought up so far. CRPG is certainly a greater concept, but no one's ever made a computer role-playing game that comes close to reaching its amazing potential.
Doom deserves to go down in history as the most addictive computer game ever. It's amazing popularity was literally shocking at the time and is still hard for most folks to accept today. Describe it, and they just don't believe it.
The only computer game that can make a case for being more popular is WoW. Its success doesn't defy belief like Doom, but the numbers speak for themselves. Like it or not, WoW is the all-time king up to this point.
Games that were just as significant but went relatively under-appreciated include Daggerfall, Gothic and Tie Fighter, IMO. But the single most-glaring omission is Ultima Underworld.
