When I said the Attic dialect is more "authentic", of course I meant in reference to Athens. The problem is, Spartans would use the Doric dialect, which would mean all their Ancient Greek names in the game should ideally be revised, but I didn’t manage to find an Attic to Doric translator. One could follow some transformation rules, but would be a bit time consuming and error prone for a non-expert.
I think there’s a balance to find between resigning too early and staying overly stubborn.
If you feel like your teammates are still enjoying the game, still have a decent economy or population, then there is always a chance to come back, even if it’s small. In team games especially, one player being behind doesn’t necessarily mean the game is lost.
On the other hand, if people start resigning too quickly, then a huge number of games would basically be decided on the first rush. We’d probably see something like 70–80% of games ending right after the first big fight, which removes a lot of what makes team games interesting: comebacks, coordination, and late-game decisions.
So in my opinion, it’s less about whether you personally think the game is lost, and more about the overall situation of your team. If others are still in a good position or still trying to play it out, it’s usually better to stay and see where it goes.
