These two criteria are not sufficient when winning the games offer life-changing sums of money and prestige. A star NFL quarterback with a $100 million contract may well still play the game even if it's unfun and if people don't want to play with them. More generally, competitive games quite often degenerate into a "whatever is within the rules" mindset, and that's perfectly fine. Since this is top of mind right now, and since perhaps someone out there may have not read it yet, it's worth linking to David Sirlin's "Playing To Win" - http://www.sirlin.net/ptw http://www.sirlin.net/ptw - the book is about competitive fighting arcade games like Street Fighter but it covers many other games and the philosophy is enthralling.
