Welcome to the site! The "platform" field is kind of confusing; it's more like which version of the game you're playing. For instance, some games actually have completely different content depending on which platform version you're playing. If you're like me and want to capture as much data as possible, you can use the "Played On" field (if you're on mobile, you may need to expand the "Advanced" fieldset at the bottom of the "Log" modal) which will feed into your console tracking stats.

As a longtime Doom fan I strongly recommend playing them in release order:

Doom
Doom II
Doom 64
Doom 3
Doom 2016
Doom Eternal

Each one very much builds off of the last, so if you go out of order it can feel weird like you're going backwards. Glad you enjoyed it and I'm super looking forward to seeing your impressions of the others! You have an intense and bloody journey ahead of you!!

@cowboyjosh Thanks for the info on the platform field!
I don't own Doom II or 3, however, after playing this game, I am looking into buying both games so I can play them in release order! Whenever I can, I try to finish all of my games in release order. 👍

If you get through the official games (3 is pretty skippable imo) and still want more, this game has an amazing modding scene that's been active since its release. There are some mods that are officially supported on the console ports, but it's also quite easy to set up a fan source port on pc and have access to thousands more, and it will (quite literally) run on a toaster.

@Silverhand ooh, okay. I did see something in Doom 1993 that I thought involved mods but I wasn't sure it was true. I'm definitely going to look into them once I've played through them.
