Re: Gate Camping Perpetuum endorsed sport
Stacks of doom were definitely an issue up into civ4. However civ5 basically killed that problem, so island based maps can be substantially harder than continent based maps because even a *** ai setting can defend against an attack much easier because there are generally less tiles to spread a death machine onto. Also: cities can strike vessels.

And to answer the question posed by the above necromancer: teleport nonsense abilities are at an all time high.
Try the Fall from Heaven Civ 4 mod/total conversion, its in a fantasy setting and there's quite a few awesome ways of circumventing the allmighty stack of doom (rooting with magic, AOE with magic, etc). Makes the whole experience a lot better imo.
