I'm so sorry, Sam. My sincere condolences.
I can't claim to have known Megalyth all that well, but we exchanged quite a few stories and messages back in the day and would sometimes hit each other up for chats over Skype. This is about ten years ago, now. I still remember the first time we called each other to discuss something other than the game Doom... we spent an hour or two talking about some of the pie-in-the-sky activities we were hoping to do or thinking of doing in the future. I remember it well because it was when I was first finding my feet in the community and we were both getting caught up in the excitement of contributing to something "big", as things go here on Doomworld. Megalyth made me feel welcome, and, among all the names and aliases that I would come to know over the years, he remained one of the few that I actually spoke with... just for the sake of having a chat.
Megalyth was an integral part of one of the most celebrated creations of this community in 2011/2012, Doom The Way id Did, and I would sometimes look to his works during development as we shared many similar goals... and also because he was doing a damn sight better job of meeting some of them than I was! There's a great deal to admire about his creative works. We also often played duels together and tested each other's stuff. He contributed one of the most regularly played duel maps during the development of a multiplayer level pack called CGI in 2015. This map — Pot City — is also his first credited work uploaded to the archives from way back in 2002.
It's very silly, but we had a running gag for many years that we would some day together create a Scatman John sound replacement mod for the game. Something to the effect of hearing random "bee-bop!" and "skee-bap!" sounds every time you interacted with anything in the game world. I think we both knew it was more funny in theory than it would be in practice, so we were happy to leave it at that. And so we will.
Rest in peace, buddy.
