Growing up in Sheffield with a C64, the ONLY place to go on a Saturday morning was Just Micro on Carver street, the original home of Gremlin Graphics. They used to have early demos of upcoming projects. Was such a welcoming and fun place to be.
Micro fun at Hillsborough was also great, and used to stock less mainstream stuff, and would take specific orders.
Electronics Boutique also became a must visit, from where I bought the Action Replay cartridge.
Used to regularly buy Cassettes from WHSmith's and Boots for my ahem, backups.
Looking back, with the cheap bus fare at the time (2p !!), I used to travel all over the city for my gaming fix.
Once I had my Amiga, it was EB, Game, and a Virgin branded shop. And a company called Gemsoft right in the centre for repairs and hardware.
