Trust me I genuinely don't know if I've ever been more baffled in my life then when I found out there was only like 2 or 3 lost fnaf fangames that had been reported as lost, obviously this was a year before the first lost fnaf fangames iceberg came out and now there's thousands of people who know about lost fnaf fangames, but that is still a very small number.

The FLM community is the only community on the internet where the average user can name more than 3 currently lost fnaf fangames, I've been seeing people go to other fnaf communities and even lost media communities to ask if anyone has a lost fnaf fangame, but the reality is that less than 0.1% of those people have heard of the game you're asking about let alone would still have a copy, it could maybe work for well known games like Those Nights at Fredbear's Remake and Five Nights at Freddy's & Candy's, but most lost fnaf fangames that this community is looking for is something that even the average fnaf fangame fan would've never heard of.

Unfortunately it's very hard to find lost fnaf fangames this obscure and it's almost impossible to find a good place to look, the best thing you could do is try to get in contact with people who actually did know about the game when it came out, for example if you want One Week at Alcatraz 2 & 3 found maybe try getting in contact with those who commented on IULITM's video, even then the chances are slim but it's probably the most likely way you'll find someone who has the games.

There's obviously nothing wrong with asking random people about lost fnaf fangames but lost fnaf fangames are too specific for it to reach mainline popularity with just a post about a random lost fnaf fangame assuming you have no following or a small following. I've been trying to get lost fnaf fangames to reach the mainline fnaf community for the past year and a half and the new lost fnaf fangames iceberg will probably be the last attempt. If a 3 hour long video on 200+ lost fnaf fangames won't get anyone interested than nothing will unless a big YouTuber makes an actual good well researched and in depth video on lost fnaf fangames.
