Lol charliedk, that's WHY the game lets you save and reload. If I haven't explored every possible scenario, if I haven't beaten every possible ending, if I haven't scored 100% on exploration, I've lost money on the games I played.
I'd like to close by quoting Bellegar's famous last rhyme:
"Cursed be the mother that bred thee! The wench must have been a hell-spawned banshee!"
