F4LL0UT: To clarify, I genuinely hate the ability to quick save.
[ ] You have children.
I don't know how many times I died or otherwise messed up in a game because I got distracted by 12 kilos of 3-year-old jumping on me or hitting me with "a magic wand" or spilling her drink over me.
I don't know how many times I had to instantly quit playing because something messy happened in the next room.
I don't know how many times I missed essential information in a NPC dialog because one of my kids had to tell me very important things on her mind
right now.
I don't know how many times something went awry in a game because my little one had to try what would happen if she also hit some keys like her dad. And if not the little one, it would be the cat swaggering across the keyboad obscuring the screen *Meow!*
I don't know how many times I cursed the Skyrim UI developers (until I found the Block-Steal-Mod).
I also second people saying that dialog choices often are not what they seem. To choose and live with the outcome you have to have all the information. An educated guess is not enough.
Still, I can see that manual saving is not for every game. I wouldn't want to quicksave just before the next corner in a racing game. I wouldn't want to to quicksave just before firing my missile in Falcon 4. I would like more checkpoints in OpF/ArmA-CWA, but as it is the game always creates a save if you have to quit - I can live with that. It would be okay for more games to have an Iron-Man-mode like Alpha Centauri. Only one save that gets overwritten every turn - live with your decisions.
