NOT REAL CASH.

Will there be player to player trading available?

I hope i can start my own in-game business selling potions for a fair price etc.

that is what made me play runescapelong after its heyday. I could invest in products, wait a few weeks and see if they rose in price.

Say player 1 was a warrior who needed potions and the other a theif who needed a sword.
they could trade

I doubt, normally in themepark games you just do some dailies and you couple month later youre filthy rich.

Id love to see somekind of meaningful/useful in-game currency sink.

i also hope they have a great crafting system. it is a "touchstone" of the elder scrolls. so it'll be there in some form for sure. can't wait until after the first of the year when we starting getting more details.

Huh?
Skyrim is the first TES game with crafting... not really a tradition or "touchstone" of the series. (not counting Alchemy and Enchanting... or the armor in Shivering Isles)

But I'm sure they will have a whole bunch of crafting-type jobs in EOS.
