Back in '98, since that's when we got our first PC:
- Dungeon Keeper (soon followed by 2)
- Theme Hospital
- Delta Force
- Settlers 2 and 3
- Road Rash
- NFS3
- A2 Racer (this one has to be on Samor's list as well

)
- Carmageddon Demo
Great days for gaming, especially once I got my TNT2 to enable Bilinear Filtering and other flashy effects. NFS3 was droolable in every single way
