Same here! tinkering with private servers is what got me into programmig in the first place. There's something about reverse-engineering a game protocol at 15 that hooks you for life. Thanks for the kind words on the name and art!

Most of my sick days in high school were after big Ultima Online patches dropped, I believe, usually on Tuesdays. A neighbor had much faster internet - I think his dad did work from home? - so I'd download the patch onto a ZIP drive and sprint back home. Then spent the day debugging changes (client changes and network/protocol changes) with others on IRC to get SphereServer to connect again. Learned so much.
