Low-level Versus High-level Roleplay
Low level D&D play is about struggling against the [ever-present] specter of Death in a dark, lonely dungeon filled with monsters.
High level D&D play is about the monsters trying to survive the PCs.
High level play should be about your PCs having fun and going nuts with their power. Too many DMs and system designers don’t get it and don’t like it, and try to find ways to bring PCs back down to the relative power of beginner characters. Players, on the other hand, have an instinctive desire to make their characters ever more wildly powerful.
