In 1998, I worked at a branch of Special Reserve, a UK mail-order company selling computer games and parts that is all but lost to history now. Anyone who had a PC or Amiga in the '90s will know the name, however, as they advertised in every popular computer magazine. It was my first full-time job after leaving school at 17, and mostly involved working the till. They also sold pre-built PCs, and I did get involved in repairing some of the customer's computers when they were brought in. Mostly, I enjoyed 'testing' the new PCs at they came in, with the Pentium II at the top of its game and some really exciting games coming out. One game I particularly enjoyed at this time was Motorhead.
After I left that job (read: was fired), I got a job in London and decided at some point to purchase a brand new PC to replace my ailing 486DX4 system. I can't remember exactly what the spec was, but I think it was a Pentium III 733MHz, and probably had an nVidia TNT2 graphics card. It's also the machine I purchased a Radeon 8500 for, so that I could play newer games. It came bundled with a decent selection of games, including Rollcage and Alien Versus Predator (which was terrifying).
This is a selection of the games I played in this era. It is anything but comprehensive, and there are some absolutely glaring omissions, such as Command & Conquer, Star Trek and System Shock 2 (I have never played System Shock)
