Maybe when you start the game, you can be a homeless traveler, or you could simply own, like people said before, a tent. And also, the starting locations. If you start out with a tent, where will all the tents be? In your inventory space? Apartments, where will they be located? I think that everybody should be homeless, and once they get some money, they can buy a tent to carry around. And on and on until they get themselves a castle, or better.
Another thing, too. I think that we should have some other low quality home as our newest permanent home to buy/build, unless you want to save money to buy a larger home. I believe that one of them is in Tropico, but I forget what they\'re called. You know, the ones the citizens build themselves when you don\'t supply them with houses.
A word about tents:
Like Killz4Thrillz said, tents should be able to be carried around, except for the fact that they would be heavy to carry. Perhaps if you log out, your character would pitch camp and the tent would be locked, and when you log back in, some health and/or mana would be regained, and you can do that, too, whenever you want to when you\'re online. Also, maybe you can enchant or buy enchanted tents. Enchanted tents would serve different uses better(Duh). Also, there could be a thing like a tent, except higher quality and more features. Kind of like those portable homes, except with some changes.
Somehow, I get a mental picture of a wagon with oxen...
