Re-Living Old Games

The other day, I discovered a pretty cool open source program called DOSBox. This program allows those old DOS games to played flawlessly on Windows XP. So, I have been spending a lot of time playing an old favorite, SimEarth, and will probably bust of the original Civilization soon. This program does require a fairly powerful machine since it needs to emulate all the hardware. But, I have been playing on a 2.8 GHz P4 and everything has been working just like it did 15 years ago. With he exception of everything being really small.
