If land was needed for more houses, then the developers should have just made a new landmass soley for the purpose of placing houses.
I think that landmass eventually came and was called "Malas"
Although I've enjoyed working with custom houses of my own, plus working on some for other players and friends since their inception, as soon as bigger houses became available, land space availability was always likely to be a problem.
It's not so much of a problem nowadays though, due to the lower subscription numbers. Upon my last return to UO in early 2009, playing on Great Lakes (one of the better populated servers), I managed to place an 18x18 custom plot within a couple of hours. On Europa, which is also reasonably well populated, I was spoilt for choice for 18x18 spots.
Although it's a bone of contention for some of you, I actually like custom houses, but that's because my own designs were often in keeping with the location or "lore" of where they were placed. I do fully understand what people mean about the eyesores though, with little thought or imagination in their design.
Therefore I would be happy to see some of the larger pre-set house designs available. There are those of us who like to display decorative items/rares, be creative as we used to and make our own decorative creations using standard in-game items (fish tanks, fireplaces and such anyone?
). There's also the need for player communities to congregate in larger properties, for guild meetings, role play or "events" like auctions. I still remember pre-2000 Great Lakes auctions at Impy's, when they were absolutely packed to the rafters every time.
I fully understand the arguments about house hiding being a problem in PvP, therefore for that sole reason, I would vote against any custom housing, using just what was pre-set options, so long as there were selections sizeable enough to encourage the other activities I've mentioned.
For me, if there were to be any changes to the original landmass, then I would suggest that additional space is provided next to all towns. There's always been space right alongside Vesper for example, although not very much. It would be fun to have increased space next to all the towns. Perhaps one way to limit usage, that I would like to have seen if such a concept had been in the game, would have been that only guild leaders could place in these locations, once their numbers surpassed a base number of players. Would have always made sense to me that guild houses were in or next to towns.
I think it's a shame when the debate here always seems to end up back towards PvP, when there was so much more to the game. I did PvP back then, though perhaps not as much as many people who've commented, but it was just a part of the whole picture of the game I loved back then.
Forgive me for harking towards something that's going off at a tangent to the core of what we all agree on, it's just with housing in mind, that
"what if" has always been in the back of my mind.
