Medieval fantasy

Midieval fantasy is common settings for RPG and some strategy games which emphasizes:
1. European Folklore/History and its reinterpretation(e.g. Tolkien).
2. Pre-steam technology level:Middle ages technology or lesser.(steampunk is another setting that may overlap: in general complex mechanisms, machines, siege engines and gears can incorporate more modern design - alternative history).
3. Strong dualism of good vs evil. Medieval honor and chivalry are common tropes.
4. Pervasive use of magic and enhancement of items.
