You're probably better off asking this question on /v/. Here are some recommendations though:
Quake live (I'd recommend cpma over it but it's dead ;_;)
Lethal League.
Frozen synapse
Gameboy emulating (pokemon games, fire emblem, anything else fun you remember from your childhood)
Boardgames (Chess, Go, etc)

If you have a late-gen P4, there's a good chance you can replace the processor with a Core2 Duo, Core2 Quad, or Socket 771 Xeon for $30 or so.

>>96247
Emulate NES and SNES games with higan, GBA games with vba-m and NDS games with No$GBA (which runs on any toaster, though kinda looks like shit).

Dwarf Fortress doesn't have low requirements, what are you talking about? It has insanely high requirements because of how it tracks every single nerve on every single body. Also it's single-threaded and poorly optimized but still. It's huge.

DF's main requirement is a fairly modest amount of RAM (including physical and virtual), and the biggest performance bottleneck is RAM latency.
Of course, the better the machine, the faster DF will run and the better it will handle more NPCs and more territory, but in principle, it does run and it can be played even on a Pentium II.

>>96834
That's the same requirements "meteorological simulation", "computational fluid dynamics", and "modelling nuclear weapons" has.

>>96882
My point is that it runs and it's playable. Compare that to the endless string of games such as Crysis, DotA, etc, which can be installed just fine, but will neither run nor even show a visible warning message on older machines.
