@ArmorPlatedLike I said if you say something to me I'll respond, for both good and bad. I'm not really worried so much as, trying to determine whether I should bother? Limited time and all, I'm sure everyone's been there, so I like knowing what I'm getting into or not and that does involve asking questions and seeing where the GM is going with this.
Here's the thing, as I see it, on your infinite possibilities multiverse: even when it's done like that it is actually defined and presented to the reader/player in some way. There's an acknowledgement of the setting as such, a way to frame the narrative within this and make the particular focus point relevant, usually even some level of defining how multiversal travel/interactions happens so the setting isn't just making new things up whenever. Michael Moorcock's moonbeam roads, RIFTS' holes in spacetime, etc.
Maybes don't have to be maybes because the GM is/should be in the position to define on some way the basic structure of his setting (you yourself say the given information as an OOC looking to start an IC would be cause for worry), and doing so does not mean it wouldn't be open ended for a huge variety of characters or that it wouldn't work with player contributions to the setting.
@SierraOkay but you acknowledge that there's merit to the points I brought up? Why would I be roundabout about a question or how I see a potential issue? I don't expect a GM to be roundabout in telling me things in their game are gonna be a specific way or another, but reasons are nice so I can understand why and how the game ticks and how to play to it. Again, setting/worldbuilding discussion. Ignoring my post for a moment, you would ignore valid concerns, questions or advice if you don't like how they were worded?
@CaptainSullyPlated covered what I would've told you.
