What games can run on a 2.4Ghz Pentium 4?

[Josh likens]

Hi, I have a old pc for my little brother, and it has no graphics card, a 2.4Ghz Pentium 4 and 1GB of RAM. AssaultCube works fine, Sims 2 works at 20 FPS, Any GOLDSRC engine game runs smoothly, GTA 3, Vice city work at 20 FPS, Minecraft runs at 10 fps. All games have been set to the lowest settings possible. He wants to play Garry's Mod but the game closes on startup. I've tried swiftshader but it just makes the window all green. If I open task manager it's borderless, has no title, can't close, needs a logoff to close. Can games like Call Of Duty 1 work? The OS is Windows XP.

Shadow Warrior and some Visual Boy Advance ROMs should work on an Intel Pentium.
