Why don't many modern games have save slots?

90% have chapter/level/mission select where you can visit your favourite spot within a few minutes. 9% have save slots, so you must be the unlucky one to play the other 1%.

Seriously though, which game are you talking about?

Batman Arkham series. For example in Arkham Asylum there is a trophy for KOing all henchmen at Joker's party which is at the very end of the game if I'm not mistaken and if you were not aware of this trophy beforehand and ignored the henchmen then tough luck.

Don't remind me...
