I think Doom is probably the best example of an influential game since its shareware model and garage-developed quality (as well as the programmer as celebrity) is more prevalent than ever. However, I'd like to nominate the game Myst as being the most important game of the 90's, for setting the follow benchmarks:
1) Graphics: a push toward photorealism (pre-rendered or otherwise), setting the bar for home entertainment.
2) Popularity and Sales: the best selling PC game until 2002, when it was supplanted by the Sims. It is also something a cultural touchstone, having penetrated the mainstream more successfully than its PC brethren.
...and more controversially...
3) The simplification or dumbing down of a player's ability to make meaningful choices in the context of the game: the advent of the binary of good & evil, and the beginning of the end of "pure" adventure games.

You know, because I feel like there's a give and take to this. A design choice works in one game, so you start to see it spreading across different titles. Except that in the end, you're just fooling around with the same mechanics but only with a different appearance each time. We look to these "important" titles for the next new thing, but they end up corrupting the marketplace.
