Tempest 2000 for £5, not THAT long after it was current. On CDROM. Copied the actual program part onto a floppy (it was only 1.3mb) and played it on the 486s at school, which were just fast enough to make a good fist of it. Excellent game. I'd quite like to see a HD remake of it, so long as nothing was changed except the resolution...
Recently picked up Sid Meier's Railroads for £2, but time will have to tell whether or not that's a good deal or a waste of a coin.
Too bad I have no real idea what "John Woo presents Stranglehold" is, or whether I'd want it / if it's any good. Because the same place I bought SMR from is selling THAT for... 7p. One presumes it's a typo and it was meant to be £7... or £4.97... or even 97p. But no. Seven pence. If it's still there next time I'm in, I may just buy it as a cheaper and more attractive alternative to using a dead DVDR as a drinks coaster.
