'Artistic freedom' is about not following rules. Or, at least, bending the rules in a way that surprises or shocks people.
Ah, I think we're getting to the core now. I think that this isn't actually about animals and why it is / is not realistic to have them in PS. I think it is about people wanting to do whatever they like, regardless of what the settings says or implies, or what is stated to be OK or not. IOW, it's a veiled version of the "It's Fantasy!!!!!" non-argument.
If everyone does the same thing - e.g. you're forced to have 'Yikass', and 'Manteras' and 'Pikachus' as pets, and nothing else, because nothing else exists in Yliakum - then you're limiting the characters.
Yup, you are. And rightfully so. Just like you don't RP spaceships, or guns in PS. It's called "settings", and a pretty common thing in RP. So unless you're leaving PS and making your own RP world, you'll have to stay within PS's one. Artistic freedom also doesn't mean that you can do whatever you like. People will still have to get what you're saying.
You may bend the rules to, for example, have a pet that isn't implemented but planned, or to have an animal as pet that isn't implemented as pet (like a clacker). But you can't RP things that don't exist in the settings, or that cannot be reasonably assumed to exist. It's why few poems consist of jumbled characters.
Maybe they want to RP that they have a raven or tiger as a familiar (maybe it's their friend, maybe it's so they can RP situations where the raven can scout ahead and tell them things telepathically), but there's no Planeshift version of it yet, so they are thusly not allowed to express themselves artistically.
If it's planned to be in PS, then OK. If not, then no. How do you RP something that you don't know anything about? Replacing it with RL things isn't OK, because it'll obviously conflict with the PS version later on. You're invalidating your "art" in doing so, and that of all others who play along with you, too.
I don't have a problem with having original animals added, but I think we should be able to do what we like as far as personal pets go.
Because personal pets realistically come into existance by the owner's sheer will, and therefore don't need to be bound by any stupid things like genetics, or just general realism?
You are prefectly fine to do /tell RP with yourself, RPing chasing your pet Ulbernaut through your space station while shooting Kran at incoming mecha-ravens, as long as you don't tell anyone.
Speaking of ulbernauts... the number of "characters" who allegedly own a pet Ulbernaut is astonishing, especially given that an Ulbernaut is neither stupid nor peaceful, nor small or easily intimidated. IRL, pet tigers aren't working terribly well, and these are
small compared to Ulbernauts. I therefore think that there is some problem with some people's RP, and with this argument of yours, since obviously one can't even RP everything as pet that
is in PS.
Next thing you know, there'll be rules about being crazy ('cause crazy people were stoned to death), or maybe being evil ('cause evil people were put in jail or hung) ...
Yes, there are. There are rules of common sense. Just how well do you think a plain murder is going to go in plain daylight, right in front of two armed and alert city guards? Not too terribly well, one'd think, yet people "RPing evil" tend to conveniently forget the consequences of their so-called "RP". Just like with those RPing annoying characters, who conveniently forget that when annoyed, people get, well, annoyed. And react accordingly. Even in a world of magic, people don't have endless tolerance. Troublemakers are still punished or otherwise gotten rid of. And if you're not willing to RP along with the not so nice consequences of your "evil RP", then I think that you're not actually RPing, but merely OOC-ly annoying.
