Man oh man, so many memories...
Elite (obviously!) on the BBC. My brother and I sitting in a dark room with nothing but the glow of the scanner and cockpit gauges
A mate of my brother bringing round a Megadrive not long after launch, playing Altered Beast "Rise from your grave!!!"
Chucking tons of money into the arcade machine version of Atomic Runner at my local swimming pool, and then finding it years later on Megadrive
Going to the local Pharoh's video rental store and their back room being full of games, then having to pay 50p extra to get the converter for imports
The intro and music from Mechwarrior 2. I can still listen to the soundtrack today and feel like i'm stomping along in a 70t mech
As Jenner said, the installation for Command and Conquer. All the FMV in that game was amazing... oh and when Kane shoots Seth in the head!
Red Alert... Einstein: "Time will tell. Sooner or later, time will tell" *fades up into Hell March*
