In Final Fantasy Tactics, there's two successive battles before you fight Velius. You're given the option to save your game in between the two fights, which I did. The problem is that the fight against Velius is fucking brutal. I got my ass handed to me over and over and thanks to saving right before the fight, I didn't have the option to go back to the world map to level. I thought I'd have to start over from the beginning of the game (which would have meant many many hours lost) but I finally managed to win with some tweaking of my party and a lot of luck.
Haha, I've done exactly this, and it was the first thing that came to mind when reading the topic title.
I managed to get out of it by entering a cheat code with a Gameshark that gave everyone +1 in movement.
This is also what taught me to always make extra save files, just in case.
I don't think I ever felt bad in a moral sense about a choice I made a video game. they're just games, nobody actually dies. We're just exercising a little bit of control over how we experience the story. I don't feel bad about any of that.
I've felt bad due to how my choices impact characters in game many times. Most recently in the Zero Escape series, every time I made a bad vote.
It's because some of the characters build up a trusting relationship towards each other throughout the game through the choices you made earlier. Which makes it sting all the more if you chose to betray them, knowing that they still trust you to make the right call.
