The save thing is more of an issue with the fact that within PC games it's pretty pointless to warn you to not turn off your console/PC because as noted no one just flips the switch on their PC mid-way through a game.
Save icons specifically I remember reading awhile back the suggestion that consoles have a unified auto-save system/icon, then you don't even need to teach people each time they load the game up what particular icon you're using to represent as auto-save. Which lead to one guy dying in ME2 because I thought it was auto-saving, not giving me a "paragon" trigger thing.
RTS game do make sense to have weakened units do weaker damage. Yeah within a JRPG sense it makes sense for the last hoo-rah of bosses but JRPGs tend to have quite their own little set of tropes. Few games here n there do have weakened armour/weapons.
The cutscene thing is pretty sane and reasonable. And there's plenty of films where I wish I could grab a separate volume slider for music, effects and dialogue.
