But, it's interesting that Gandalf inspired decades of mage / wizard characters who broadly shared common themes: using magic to do direct damage, not wearing armor, not using swords, being physically unimposing, often being old men, etc.

How different would modern fantasy and TTRPGs be if people had been inspired by different parts of Gandalf's character. Like, we might expect Wizards / Sages to lead an army's charge, despite not wearing armor or doing direct damage. A typical fantasy wizard / mage hangs back and lets the people in armor lead the charge. We might expect them to have incredible perception, seeing very clearly, sensing danger nearby, etc. A typical fantasy wizard / mage / sorcerer is focused inward and often the least perceptive one in a group. We might expect them to be physically fairly strong, at least enough to fight with a sword. We might expect them to be loners, rather than wanting to join adventuring parties. We might expect them to do mostly cleric-ey things like heal people, boost morale, strike fear into others, etc.

Instead, people adopted the physical appearance (minus the sword) and tacked on a lot of direct-damage magic. For TTRPGs that makes sense because you can't have a character who's both physically imposing, extremely charismatic, able to fight with a sword, and also capable of using magic. That's just too powerful for one character. But, I also can't think of many fantasy books or movies that have a strong, perceptive, brave sage/wizard character.
