My two cents on this - I'd really prefer to be allowed interaction in the forum, but if the mods have already decided otherwise/the majority thinks that a non-interactive worldbuilding forum is better, then it is what it is.
The guided adventuring systems a few regions had were very different from what you guys do in RPT; systems like
this and
this. And they were fun, and generally well-received but I do acknowledge that a possible issue with such systems is that it really requires the region/world creator to continue running it and give players direction (much like mafia games - they don't work well without an active GM), and if the creator can't keep up, the activity in the region dies. Actual RPing should stay in RPT, I agree with that, but stuff like this, while it's "roleplaying" in a sense it's clearly not the same as what goes on in RPT and there's currently no place for it on PC.
Honestly, if this will be strictly for worldbuilding, I'd like to take back my vote if it's possible(?) and just push for the pet forum - absolutely not to spite anyone but I just really don't see myself participating in a forum solely for the purpose of worldbuilding and I don't want to be responsible for voting towards a forum I have no interest in.
I'd really like to hear from other people who have voted for the forum so far, though! Worldbuilding is clearly something that's kinda hard to define and we have a few varying views on what it should be right now, so some additional input might help narrow down what the community is actually looking for, if there
is interest in this kind of adventure game or if people are just looking to create worlds. :)
