Oh my bad
I was referring to this
https://gamejolt.com/games/sonic-exe-the-game/16239
MY5Tcrimson was the name, he was the first to make a more or less 1:1 recreation of the creepypasta as a game, it was very popular (also somewhat annoyingly a lot of people obsess over his "version" of Sonic.EXE since it is slightly visually different so they consider it a different character from Sonic.EXE and just call it MY5Tcrimson EXE or something. This kind of thing is one of the more annoying traits of the community in my eyes.
He also did a recreation of the Sally.EXE story (a creepypasta that came not long after the original and was notably worse and also plagiarized from some other story infamously). Sidenote, I think EXE shit might be the most lasting impression Sally has made on the Sonic fandom since, with Archie being dead and ultimately pretty forgotten, you could argue Sally is more well known in the EXE side of things since she was fortunate enough to appear in the early creepypastas and games to the point where she still shows up in new EXE stuff like The Disaster and Outcome Memories, keeping her alive for a new generation of Sonic Fans. A weird situation, to be sure.
The other two games I mentioned are the Nightmare series by JaizKoys

and the Spirits of Hell games by Dan

These were really popular back when as well, the big tentpoles during the before FNF EXE era. They feature original stories with their own versions of Sonic.EXE (Exetior and Exeller, respectively) alongside other evil characters. Lot of alternate endings and bad gameplay abound.
I think their might've been another relatively big pre-FNF game I'm missing, not sure. There's the pendrive azul stuff, but that's another can of worms.
I find it all pretty fascinating in an autistic way.
