i don't often watch playthroughs so that when i get my hands on software to play it i have no gameplay point of reference HOWEVER upon looking on youtube RuminInLove has a playlist for a 100% walk-through for i believe all games (at least 1-3) however like i said earlier i don't frequently watch gameplays so im unsure how funny/problematic he may be 💔 i do suggest looking up silent hill (number) long-form let's play as there's many multi hour videos of playing through and getting at least one ending for the game, if not going back and getting all the endings. i hope this helps, sorry if it doesn't that much!

i personally recommend watching gameplay of 1 and 3 back to back and then going into gameplay of other games as those two are very related as ive said in a other answer ^__^
