Real Money Transactions are prohibited, so our Wurm possessions have no conceivable value.
A player may move or transfer virtual Wurm items, but that can never be a real payment.
A player can never receive anything of value through using the Wurm Online game.
Whatever the answers may be,
some thinkings and wonderings:
What is a "form" of payment?
Coin is a form of payment.
Could a payment be formless (intangible)?
Does a person's word (their promise/pledge) have value enough to be payment?
If a player hosted a free public lottery/drawing, what if he was doing it all for the smiles and happy words? That is the payment form received from the participants.
What is subject to "chance" in the software?
Is the 'random number generator' (the pass/fail element in Wurm) truly a random number source?
Even a 'true RNG' would be delivering a result at the timing of the user's actions, so what in the world is truly up to chance anyway?
Are "moments of inspiration" influenced by such randomness? Or is that "window" for the player's action unchanging?
Is premium required to participate in any activities that utilize elements-of-chance to yield assorted rewards?
(coin/premium is available in game, without ever making a real-world transaction in the Wurm Online Shop, so I suppose the payment is not "required")
Easter Eggs may be claimed by premium players, but are their contents pre-determined? (or according to a schedule/formula?)
Rift participants' rewards are from a list of known possibilities, influenced some by their performance, but does a free-skilled player even have a "chance"?
