Are there any maps similar to the original ones?

I don't want to impose, but since you asked, I recommend my "Asatamu" and "Preserve" maps; perhaps also "Land of 1000." The maps aren't perfect; there are significant imbalances, and "Preserve" might even deter players with its monstrous creature growth. But generally, regarding "rare resources," I'm currently working on something in that direction, without trying to overcrowd every square meter. Maybe something will come of it in a month or two. It's funny, of course, but I hesitate to advise someone else, because I have a similar issue. Although, despite similar priorities, I still liked Samatron's map, "In Search of the Lost City," at least the "starting part"; after that, it seems to devolve into all sorts of dragon legions. There's also OldMage here; he might be quite different from what you're looking for, but he's good because he brings his own, unborrowed style to the game, which is quite self-sufficient. And "Combat Gauntlet," which I mentioned, is a map from "Armageddon's Blade"; in English, it's called "The Gauntlet."
