If you don't already read Fabien's blog then you should.
Some amazing memories in there. I should really do the same and dig out some game's out of storage to put on a shelf. I sadly have lost so many of my older games over the years, basically all of my PC stuff has gone. I do have a fair number of console games and some Spectrum titles including a Last Ninja 2 box, though I lost the ninja mask a few years ago or at least misplaced it.
This guy's articles on the idtech engines are fantastic.
