Any suggestions for old games that run on Windows 2000 in VirtualBox?

I recently started getting into old Windows games, and so I installed Windows 2000 into a VirtualBox with 1GB RAM. I've tried running:

The Sims

Age of Empires

Star Wars: X-Wing vs TIE Fighter

Out of those three, the only one that won't work is X-Wing vs TIE Fighter (doesn't think DirectX is installed). Are there any games that will most likely work in a VirtualBox?
