I read that a multiplayer verison was not going to happen with the series.
Thank goodness.
But the idea got me thinking, what if it had a mailing system of some sort. What I mean is you can send items, collectables between players (books, decor, custom/orig weapons, spells, potions, recipes, etc). I think that interaction would be awesome to have.
I don't know, I can't really see it to be honest. Theoretically every copy of the game will have all that already, you just have to find it - unless it is going down a Pokemon route, which wouldn't be a good thing. Plus there would have to be a good reason for trading, otherwise you end up with people getting the best weapons in the games at low, low levels (and I don't know what they would be trading in return to someone who has the best weapons and can be giving them away).
