Yeah, it's a shame how this keeps happening. It's why I opted for the PS4 version of the Tomb Raider collection last year, rather than going with the PS5 version.
I wonder if with the release of this game if it has any effect on the price of the PS1 versions? A lot of the time retro games go down in price but sometimes they shoot up instead. I know Silent Hill on the PS1 recently got a price bump thanks to the release of the Silent Hill 2 remake. Granted, not the same kind of situation but it's always interesting seeing the prices of retro games being influenced by modern releases.
