Soccer is a SPORT

Demigod is a GAME

There's a difference.

You can also come back from 4-1 down with 10 minutes left, since you have scored one goal there is no reason why you can't score another 3 in the remaining 10+extra minutes. Also watch an EPL game, professional athletes don't waste their time trying to win lost causes. Managers will substitute their best players off in a drubbing to save them from possible injuries. There are times when you know you have lost, and in videogames most people quit. 

In a game of demigod, if you are outclassed in every department by strong early or mid game characters the game will be over by the 15 minute mark. The game wont actually end until the 20-25 minute mark in many cases. Why waste everyone's time playing out the rest of the match?

Want to hang around and get slaughtered for 10 minutes? Sure, I'll beat you to death while you're at your crystal if you WANT, but is that really going to help anyone? The truth is that if you didn't pick up on what I was doing to beat you in the previous 15 minutes, you're probably not going to magically come to a eureka moment and figure it out in the 20th while im pounding you last towers down and locking your portals.

What if I'm on the losing team? I've been playing since beta and I don't often get outclassed in a 1v1 situation, but in a PUG I could be playing with poor players against a team of good players. We are going to lose. Badly. I'm not going to sit around for the 10 minutes at the end while they consistantly beat me to a pulp, I will say my gg's and wish them luck in their next game.

Once the concede button comes in, I'll use that, but until then its going to be good old fashioned leaving.

If you were playing in the same room on a LAN would you also just get up and leave in the middle of the game?

Yeah why wouldn't I...if I had to take a phonecall, or answer the door, or go to the toilet, or do any number of things I would either be AFK and useless or leave if I was going to be away for a while. I'd tell people where I was going first.

Unless you mean a LAN with randoms. I don't go to them so I honestly have no idea. Got internet and stuff...don't need pub lan

How about if you were playing a board game?  Just get up and walk away.

You're removing the reason for leaving. If i was playing a board game and it was no longer fun, I doubt my friends and I would continue to play. We'd probably do something else. Demigod isn't terribly fun after the game has been decided. Sometimes this is only for a tiny amount of the game at the end, sometimes is stretches from the first kill all the way through, as someone realises that they are hopelessly outclassed by their opponent. Would Roger Federer enjoy playing against me in tennis? I really doubt it. I don't think I'd enjoy a game of Demigod against him either. If perchance we were put into a match against each other, the etiquette associated with sport doesn't allow me to simply concede a game of tennis. Roger on the other hand can quite easily concede to me in Demigod (assuming his alias isnt Ke5trel or something)

If you outclass the other team in every department by strong early or mid game characters do you leave when you are on the winning side?  Why not?  It's obviously a waste of everyone's time playing out the rest of the match.  You already know you've won.

I don't need to, my opponnents will leave since they will reach the same conclusion, say gg, and concede the game.

If they don't concede they must know something I don't and thus I will continue to play in order to find out what that something is. MAYBE they saved up all their money from the start of the game and that's why we're trouncing them, and they're about to unleash ashkandor on my poor little leopard to turn the tide. I DONT KNOW, but THEY DO. This is why THEY will concede rather than me declaring myself the victor to end the match.

I believe the distinction between a sport and a game is in the competitive nature. Sports are played, like games, for amusement and enjoyment, but they are primarily competitive. They are a test to see who is better at some physical activity. A game on the other hand is primarily for amusement, with competition merely a by product to enhance the fun of playing. Demigod falls into the latter category because nobody takes it seriously enough to consider it a sport, everybody plays it primarily for their enjoyment. There is no prize for winning, and thus the closest analogue in sport would be a friendly. Even that is a stretch.

This thread is worse then watching an abortion debate.
