I know there will be none, but what if I drop something? does it disappear?

Also there could be some objects possible to pickup or kick, not much hope for this.

We know you can pick up objects, no idea if you can drop them, you may have to delete or sell them.
We'll have to wait and find out.

I mean not just pickup and hide into inventory, but more like move and throw around.

i highly doubt it. imagine people all having items thrown all over the place?

They originally wanted dropped items to appear in the environment, but they quickly realized that people would destroy the server with cabbages and decided to axe the idea.

This is one of those things that just doesn't work in an MMO. I'll never forget when a guild decided to crash our WoW server by laying out feasts until the game went down.

yes, that's why I doubt, but if it could be in Inn only and chairs could do some damage, hmm, anyway not possible in general for MMO.

Throwing stuff around is best kept in the single player games, as mentioned this would be abused to hell in an MMO.

what part of MMO eludes you ? =)
