There was an element to the online game which especially involved the Battlefield and playing ladder games, and these games did tend to be played over-aggressively and cheesily by people whose only intention seemed to be to win at all costs, regardless of what exploits they had to use. Fortunately most of those people seem to have moved on, and people don't play ladder games now, so the games tend to be a little more civilised.
However there are still one or two players at Gamespy who are still a bit that way, and so some people will quit under a variety of situations, and give a variety of explanations, but essentially it is usually because they had a bad start, or someone else had a much better start than them. Sadly they can't see the irony in them wanting to solely play random maps, and never play custom maps, yet they don't like like it when they are randomly given a poor start. If they played custom maps, it would be much fairer in terms of distribution of resources.
Regarding playing with turn time limits, it very much depends who you are playing against. I am happy, for example, to play BNW3 with TC always and no turn time limits, PROVIDING that I am playing against Kirky Picardo and Megamanx, for example, who always end turns without undue messing about. If I had some of the Gamespy regulars in a game, such as True Purple or Karfhud, there is no way that I would agree to playing without turn time limits, as when we play with 3 minute turns then, after about day 5, they will never actually end their turns before the three minutes is up. This means that a game that should take four hours will actually take six hours, mainly due to their lack of consideration for the other players. Also some people (especially Americans) seem to assume that the whole world is in their time zone, and don't take into account that for the European players it is the early hours of the morning and there is an element of urgency to finishing the game.
That is why I have come to the conclusion that it would be nice to find a few players that would like to play custom maps, people that are fun to play against, aren't intent on winning at all costs and don't quit when they aren't doing very well, and where we can reload a map at a later date without fear of them having cheated by opening up the map. Most of the players that fit into that category don't seem to come to Gamespy any more. Examples would be Kirky Picardo, Oakbow, Stranger, Joepo, Jomungur, Sim Rogar, IgorT, Swolte, Karfhud.
But I aplogise, this thread is supposed to be about Dwiggs mod, not about the trials and tribulations of online gaming, so we seem to have gone slightly off-topic.
