Make the story automatically skippable. Every time. Many games explain the mission/objective in a short sentence or in the minimap anyway. Don’t make me watch a long cutscene or press/hold a button to skip the dialog. I’m never going to care.
Always have a tutorial or practice area to remind me how to play the game after I put it down for a month or so. Bad enough that the controller map is hidden in the menus (if there even is one). It don’t help much to just say what all 16 +/- buttons do, depending on what mode I’m in. I have to actually use them to get back into the swing of things, and I’d rather not jump right into the action (and potentially lose progress) right away.
