I got two stories to tell.
My dad once got me a steering wheel for my PS2 along with a copy of Burnout 3: Takedown, I got a memory buried in the depths of my mind that there was a free roam mode where you could drive around freely. The map was set at night and there were instructions at the top of the screen showing you different methods of how you could slam into other cars, akin to what the tutorial cutscene shows you but with white outline illustrations.
I've played that game several times over the years but I've never found that mode again, I've tried digging through the menu's, starting the game without a memory card but nothing.
Years have gone by and I've seen absolutely no mention that Burnout 3 ever had a sandbox mode.
So I guess that was a complete Mandela Effect, I still haven't figured out what my mind actually remembered that day.
My second story revolves around an old PC FPS game called Mortyr from 1999, now strap-in because this story reads more like a creepypasta.
As a kid, I used to be really dumb with how I approached downloading new games. Whenever I saw a cool game on the internet whether it'd be on Youtube or somewhere else, I'd search for it on google with a "{GAME NAME} download for free no survey" search (bricked lots of Windows XP's and Vista's with that method).
At some point I guess I decided to download that game Mortyr, now my recollection of the event is very foggy but I remember launching the game and it immediately booting and fullscreening into some sort of church level where you had a knife and some nazi soldier was in front of you. A little deeper into the church you fought more nazi soldiers and got a gun or two.
Playing it felt like a fever dream because the game just booted me in just like that, no menus, no launcher, just plopping you down into a church with a knife and nazis. Plus the HUD was either so small I didn't notice it at all or just glitched out on me leaving me with no HUD. Felt like I was playing something I wasn't meant to.
What's worse is that there wasn't even a pause menu, somewhere within the church I got stuck and couldn't find my way out, so I pressed the ESC key to bring out the pause menu so I could quit but to no avail. Then I tried quiting through the classic ALT+F4 combination but still nothing happened.
I even tried pressing CTRL+ALT+DELETE to bring up the task manager but that screen wouldn't even open. If that hasn't sounded like some lame ass creepypasta already then this part will, I tried shutting down the whole computer with the power button but it still didn't work, I kept on clicking it but the computer was still running (Though I never knew about holding the button down for 10 seconds to force it to shutdown as a kid, It's possible that Windows just fucked up and took too long to shutdown).
I remember having to unplug the whole damn computer from the wall socket.
Not sure what the hell happened but I don't think kid me knew what the fuck happened either.
I don't recall ever launching that game again, in fact I don't even have a recollection of how I even installed it.
Over the years, I've tried doing some sort of "research" on this whole event but I always came up empty.
What I always found was that the first level in the actual game strongly reseembled what I remember playing, but It was never the EXACT thing. I never got far into that game so I was pretty sure my memory of how it looked like was clear, but I guess that part could've been a Mandela Effect.
That was until a year ago, when I finally got some sort of "closure".
After retelling this story to my friends, we went snooping around on the web to see if anything like that has ever happened to anybody.
Amongst similarly asked but completely unrelated topics from forum posts, we were able to find a video that was showcasing a "Demo Loop / Attract Mode".
Whatever this "Demo Loop" was, It was EXACTLY the thing I remember playing as a kid.
It wasn't a Mandela Effect after all, this "Demo Loop" level used an early version of the first level which is why the one that's in the final product looked so strange to me.
Here's the link to the video if you're interested:
