Personally, I don't consider heading out of bounds as a method of self-destruct to be any better or different than going AFK from that point of the match on, disconnecting and leaving your 'mech behind, or otherwise 'taking your ball and going home'.
Yes it's about sportsmanship, yes it's applicable even to things that aren't sports.
If sportsmanship isn't applicable to games, then 'flipping the board' in any tabletop game when you're in a losing position is acceptable- anything from Battleship to Warhammer to Magic: The Gathering to Risk to Space Hulk to Robo Rally and so on.
Anyone claiming that MWO shouldn't have sportsmanship applied to it because it's not a sport has no ground for comparing it to war either as long as it isn't an actual war.
A tactical retreat is performed during the course of a match of MWO just through breaking off, repositioning, and reengaging. The entire point of a tactical retreat is to conserve force for re-use elsewhere, and with no resource carry-over from one match to the next, the mindset that there is such a thing as a tactical retreat on a scale exceeding the bounds of a single match makes no sense.
Applying this concept in this manner is misapplying it, and you might want to reconsider how you're thinking about this
game.
By hitting the 'launch' button, you're making a small social contract- you're agreeing to play a game with twenty-three other people. As with any other situation where you're agreeing to play a game, in person or otherwise, you have no legal obligation to participate in good spirit, but you do have a moral one. It's not a
big moral obligation, nothing comparable to not killing your neighbors' dog next time they go to the store (just to pull an example out of my complete lack of a hat), but it is a moral obligation nonetheless.
As in any other such game situation, you've thus agreed to try to win and to stick it out for the whole game, or at least until you personally are eliminated. Leaving before this time (for reasons other than something more important coming up) hinders the fun of the others playing the game. If you don't want to consider the fun of others, then the obligation is yours to find a game where you aren't playing with anybody else and thus don't have this concern. Choosing to ignore this in this situation (when playing a game with strangers over the internet) indicates one of two things:
- People you don't know personally don't matter to you. If you knew these people, you'd care, but you don't, so they can go [insert colorful phrase here]. I would like to suggest you try to figure out what the actual reason is you're playing a game with non-local multiplayer, since it's clearly not about playing with other people.
- You only care about how you look- since these berks on the internet don't know you, you don't have to worry about appearing to be a good person. I would like to suggest you reexamine your morality and existing friendships, since you're lying to the people who know you.
Games are intended for having entertainment. Games with multiple players are intended for all the players to be entertained. This is the nature of game, and the point you agree to uphold by playing a game. If you are going to break with this agreement for any reason, then you are responsible for damaging others' entertainment.
No, it's not as bad as most other forms of damage.
No, that doesn't excuse it either.
