I read this without reading the preceding comment and for a moment thought I should start playing D and D again.

Hope you're better soon and don't come out looking like you've been mugged like I did last time I was in hospital.

What about on top of a mainframe?

Hmmm,
ZX81
ZX Spectrum
Sinclair QL
Atari STFM
Atari STE
Atari Falcon
68000 based mini computer - only for a few days
Saga Mega Drive
Atari Jaguar
PC - have multiple and always will
Nintendo Wii
Sony Play Station 3 (only really bough for the Blu-ray player)

I'm the same age as one them, you can guess which!

There may have been a lot of save and reload action!

I did manage to finish this and Terror from the Deep. Had it released a year later I wouldn't have because becoming a dad uses a lot of your free time :)
