I'm running Windows 98 and I finished my first game without any problems.

just so you windows 98 users know ...there is an unofficial windows 98 service pack that fixes ALOT of 98's problems. the 512 megs of ram problem is fixed. you can add as much ram as you want once you install the service pack. I'm running a gig of ram on my computer that is running win 98. check it out at
