Having Technical Trouble Playing HOR?
Restarting windows will cure the most common HOR problems. Restarting windows may or may not cure the following symptoms:
• Choppy Gameplay
• Choppy Sound
• Unexplained "crashing"
• Any other unexplained problems

Other Problems that may Arise
As with all software, there is an absolute gigantic number of things that can go wrong, being that every computer set up (usually drastically) differs. When a restart doesn't fix problems, it's usually safe to point your finger at your computer's hardware. I'd recommend at least a 733mhz CPU, 96MB of Ram, and a relatively modern GPU (32MB or better most likely). Also make sure you are indeed using a windows computer (95,98,ME,NT,2k,2k3, or XP+). At the time of this writing, this game is not available for linux/unix/bsd, or Macintosh operating systems, however you are welcome to port the source code yourself.
