Fun Fact. My first “tech job” was tech support at EA in the late 90s. Serious Sam was the FPS of choice for late night LAN parties for the EA tech support and QA teams. Tech support and QA were shared resources. They’d shift people from support to QA in summer for fall/winter holiday releases and back to support around the holidays.
Serious Sam was the one FPS that would run decently on our workstations.
Long story but I got promoted to maintainer of the EA game tech support site which is what got me into coding.
