In this case walking faster is not an issue of gameplay, it's an issue with players being impatient. Don't take that the wrong way, it just is what it is.
Sounds like one of those "Don't take it personal but I have to shoot you" deals. lol
Here is why I want to move faster. I got a shit load of a backlog and I'm doing my best to get to many of them. I personally don't care if they make a change, I take it into my own control. Many games, esp RPG's have you go back and forth a lot, speeding that up keeps the game hoping and allows me to make it to the end. Many games I play and never finish either. We all have or wants and needs.
