Omnilium, Summoning, and Science.

[Omni]

Metagame elements
OM as a number is a way to quantify the amount of Omnilium you have. Just as you can't say "I have one water", you can't say (in-universe) "I have one Omnilium."

Incorrect. That would make doing business extremely difficult. But we don't talk about it in RPs because we don't have a list of costs for everything.

[*]Any character can summon anything within certain limitations (such as not pulling characters from unrelated media), limited only by their imagination. Some imaginative Spartan could think of a "sword made out of glowy light" and summon a lightsaber

Sort of correct but misleading. They'd see what they imagined. That doesn't automatically translate to a Star Wars technological lightsaber.

3+ minutes is mainly a metagame rule, explained in-character by "Your character must concentrate, visualize the item etc." but it is also there to prevent pulling solutions out of your ass and other imbalance issues like instantly summoning a car while fleeing a battle, and driving away. Things such as moves that summon items are more of a "supernatural power" than Omnilium summoning, and fall under a different restriction.

Misleading. It's a rule for a number of reasons.

The balancing of moves is completely and entirely a metagame element. If Camelot didn't have magic their weapons would be weaker than Coruscant's because they are not as technologically advanced, for instance. This is to keep people from having a "home advantage" by picking the strongest possible character and dominating the entire game just because of that.

Incorrect.

The number of secondaries is a metagame element to prevent people from raising armies out of nowhere. If it was an in-universe element Palpatine, Aragorn and Diablo would have armies of a couple dozens of guys. That'd be underwhelming.

Incorrect.

The OM cost of "mechanical benefits" is to limit your character's ability to obtain advantages through the amount of OM that you have. Otherwise it would be no use having a currency implemented.

Not sure what is being said, maybe partially correct.

The costs of things are a metagame element that cannot be quantified in-universe. Otherwise, why would five cellphones (Communicators) cost the same as a mansion and a small village (a Base)

Correct.

OM gain is independant of the actions of your character (walking around for 100 words or Omnilium extracting for 100 words is worth the same OM). To compensate, hand-waving exists.

Sort of correct.

dilation is a way for the site to explain how despite different speeds that one or another thread may progress and thus different Primes may perceive time differently, there is still one continuum. The only measure that we have is real-world time. We are NOT allowed to use time dilation to fast-forward the time faster than it passes in the real world (you are not allowed to have your character do a 10 day IC trip in 5 days OOC time - correct me if I'm wrong on this).

Correct.

In-Universe elements: As far as we know, anyway.

All pure speculation.
