even if you saw a greyed choice you might not know what conditions are required to trigger that choice, you still have to replay the game and try different choices to actually get that choice but you'll just know that there's a different route that you can try. but lets hope that it can be turned off.How so? It won't change your choices at all as you can't click the 'new' option.
I think a big problem of the game is that a lot of players never even realize they are missing most of the game. People are still used to the standard game that has like 2 paths (good/bad) and one of them is boring. I think most players don't replay games even once. Just look at all the requests for save games when a version comes out.
Again, how so? If you see an option you can't take you are less likely to replay the game?
