Another great year.
Lot of fantastic sequels, Tomb Raider II, Quake II, Star Wars: Dark Forces II, Riven (Myst II).
P&C adventure gems like Blade Runner and Last Express.
Ultima Online, which put focus on MMORPGs.
Diablo, that single-handedly spawned certain type of aRPGs.
Fallout, my favourite game from that year, which redefined, both mechanically (opting to move away from standard D&D model, replacing it with something much more akin to Call of Cthulhu/Runequest/BRP D100 family of games), thematically and gameplay wise, what CRPGs are and got them closer to their tabletop counterparts when it comes to freedom of choices and how to tackle problems.
But ultimately, another game deserves my vote, for it was a perfect blend between RTS and Civilization, all in a gorgeous looking and sounding package - Age of Empires.
