Tony Hawk's Pro Skater and Microsoft Flight Simulator 2000 came out in 1999 too, both big milestones for their genres. THPS had major cultural impact and brought a whole generation of kids to skateboarding, whereas MSFS2000 was more of a technical achievement, for the first time featuring the entire globe along with virtually all charted airports, around 20 000 in total thanks to Microsoft's deep pockets. You could boot it up, sit into Concorde at Heathrow, and circumnavigate the earth.
