There's a big difference in the car salesman saying "you look cool in this vehicle" when it's not true, and saying "I have a valid title to this car and it's certainly not stolen" when it's not true.
Opinion has no meaning. A lie is still a lie.
There are players in my gaming group who would never look cool, ever. We have one guy who is functionally ****** but kicks butt at Historicon, at any wargame. If his parents were alive, he'd still be living with them, instead of with his sister. I've known Gary since the 1970s. All of his allowance went to gaming. He has never even thought about dating, ever. Gary is a typical, Japanese
Otaku (yes, he is Japanese) and I know hundreds like him. Gary has always been out of shape, never even considered fashion, and has a room filled with games, models and figures, which will all be tossed out when he dies, as I've seen all too often over the years. Gary would never buy a new car, or even a used car, just to look "cool", as the concept does not exist in his world.
When picking sides for a game, Gary tops my list. I'd pick him just to irk other players, because they usually believe that he's an idiot, but Gary follows orders to the letter, without ego. Gary plays because he enjoys playing, he doesn't care about winning or losing, and no matter how many times I've trounced him, he is totally unfazed by any opponent, no matter what the odds.
When a player makes a move and Gary says "That's a stupid move." It is a stupid move. Gary never lied, because lying requires an ego. Lacking an ego, Gary was also very hard to deceive, as an amount of self-deception is also required.
Gary plays Battletech but doesn't care about universe or the factions. In Gary's eyes, the Clans are like giving WW2 German equipment to WW2 Italian commanders, they cancel each other out.
As a role player, Gary is lost. An elf is Gary with pointy ears. A warrior is Gary with sword and shield. A Paladin is Gary with a sword and shield...Gary doesn't pretend to be anybody other than Gary.
Saying that a small lie isn't a lie when compared to a big lie is a lie...and again, self-deception...
