The thought came to mind after reading a recent post about Baldurs Gate 3 here but it reminded me of the Japense only PSX game Mizzurna Falls where if you don’t perform a certain action early in the game you are prevented from getting a true ending. While this might not be a traditional soft lock because you can still progress to a point it made me wonder none the less.
I understand BG3 might be a hard lock because the game abruptly comes to a close I am not going to get into the semantics. The only other soft locks I can think of are with Pokemon.
Shout out to the fan translation of Mizzurna Falls. An article on the ROMHacking.net website can be found here.
In the same vein: the games in the Hugo trilogy had several fail states… each. Trying to cross a bridge? Oop, you’ve bumped against the wonky hitbox and dropped the matches you need near the river. They’re wet now and completely unusable.
Maniac Mansion was the first that came to mind for me. You select a party from a number of characters at the beginning, but unless you pick the exact right party, you’ll never be able to finish the game.
