I hesitate to post this for fear of tarnishing our bleeding-edge image, but…
I’ve never done much online gaming, mostly because my interests are in other areas and my home machine is a 600 mhz Celeron with a 56k modem. That said, I just came across http://gamesocket.com, which appears to be a largely abandoned online battlezone-style multiplayer tanks game. It wouldn’t load using win2k, but windows 98 is fine. When you’ve got 4-5 human players it’s pretty addictive. Would any Streettechnoristas like to get together at 9PM Pacific and mix it up? Also, are there any other low-bandwidth, free combat games out there that you like?
