My very first shipped title was for the PS2. By then, we had a development kit (called the Dev Tool) that ran Linux and had a sufficiently large hard drive that we could copy PS2 binaries onto and run. One of my coworkers would run an Unreal Tournament dedicated server on his dev tool for team network games after hours. I really can’t say what the PSX environment was like, nor anything before that. It was way before my time.
Got a burning question you want answered?
