You don't have to pick up the garbage if you don't want to. I know a lot of people who play these games let their OCD get the best of them, and they *can't* not pick something up because it's like leaving money on the ground, but that's not the game's fault. I used to do that in order to make as much money as possible, but after I beat it and found out how easy it is to farm cash from the last boss if you need some, I stopped worrying about it in subsequent playthroughs. Talk about a load off your mind! It would be nice if they added an option for certain lower rarities to not have icons pop up, though.
