This is the scale though. Sure your game is the 1 where you have non trigged events happen, but a lot of Neo T games are the 10 where everything must be player driven.Nothing in this post is true of Neotrad. I have no idea where you got some of these ideas. No, I throw things at my gamers all the time, I'm not just forever waiting for them to make a move so I can react.
Right.100%, the only thing I agree with is that it's probably not going to be random? To use above example, that wizard is likely linked with something trying to prevent the PCs from achieving an aim. Maybe it's a minion, maybe they have secured an artifact of arcane power, etc. Pressuring the players and putting barriers in their way respondent to declared goals and intents is a key component.
I don't think trad play would have a random wizard just...show up to attack teh PCs either?
The first part is just the pure DM whim. The DM simply decides to have an events happen, 100% independent of anything the characters have done. But it is not random...it is just the players don't know the "why".
And the second part is that it is not linked to the main plot or story at all. It is just an event.
