Reading that flyspray article saddened me.
I like the fact that items don't disappear automatically. It means we can make campsites out of Ulbie skins and so on.
On a negative note, I understand why it's implemented (or meant to be). Too many times have I seen a string of apples through the plaza leading to a stall, Slags left around the furnace, and other 'litter' such as books left as advertising.
What should instead be done is a 'who dropped this' tag added to the item in it's examine window so either players or GMs can inform the dropper that littering is not acceptable. NPCs buy Slag already for 0 Tria, so you can dispose of it there, apples shouldn't be put across the plaza anyway, when a simple Auction message suffices, and books, well, if placed as well as the Klyros Junction Party invitations, they aren't a problem.... but take them down when the event advertised is done.
I like the idea of buyable stalls, wagons etc, but...
1) There are plenty in Ojaveda. If people used them that'd be just as fun as popping yourself a new stall in Hydlaa (imagine if someone organised Saturday morning markets in Ojaveda) But overall I like the idea, so long as the owner cannot leave the stall without packing it up (so dropping the stall effectively turns your character into an NPC shopkeeper, but you manually speak and trade (Don't add code in the future so people can completely turn their char into an NPC shopkeeper... not good for RP))
2) Tents... easy answer... WHO NEEDS A TENT WHEN IT NEVER RAINS??
3) Wagons. Are they of any use? I support them if they're useable, but not if its just so players can dump them anywhere they please.
4) 'little towns' well yes and no. Does this mean you want a portable furnace? (Hey, that's a cool idea!) I think the fact Miners have to move to sell their stuff is a good thing, but at the same time, a mini-economy of merchants could be formed who buy Plat for 800ish Tria and sell it on to smelters for 1000Tria. this would make a little RP economy, and start opening peoples minds to more than just the Miner-smelter-NPC Platinum train we have going on... it would make people start thinking of other areas that can be merchanted at a little sacrifice to the greedy manufacturer class...
