Why coaster anything? Set it on the table. Games as coasters is trashy so it's apparent presentation isn't important. Why care about cup rings? You basically made a thread that's says you live life classless. Maybe it doesn't seem like a big deal to you and that's fine. Live however you want. But you've left the image of a guy who shows up to a high end restaurant in torn jeans and a T-shirt and is confused about not being allowed inside. That outfit isn't a 3 piece suit and a game is not a coaster. Basically don't be surprised when your not taken seriously. Perception is everything.
