Whoops. I've mentioned before that my first experience with Doom was the Switch port, before the major updates, and the same for Doom 2. I suppose my very first experience was the Shareware version on Newgrounds, but that was just as a taster. I only got into Doom last year, so I suppose there's a good excuse.
I do own Doom 64 on its original cartridge, though, and it's pretty fun, though a lack of mid-stage saves definitely makes it tougher and means I have to commit to every move.
