PBBG Domain of Heroes

I don't know how many of you have actually looked into PBBGs. It stands for Persistent Browser Based Game. They require only a browser, and store information about you. Now, I've never tried any but the RPG's, however, I've found them fairly nostalgic. If you ever played any old school text based video games, these may fit the bill.
For me, it is like one of the old choose your destiny books. Where you can take actions, and influence the quest. I've been amazed at the amount of creativity and time that have been put ino them. The current one I've been toying with, is Domain of Heroes. It is a much more "hands off" version than I've seen before, with a very interesting business model. I say hand's off, because you queue to fight monsters, and it will continue your last action, and continue brining in monsters, until you time out. Every action resets the time out, or you can walk away. I'm enjoying it, because it can be played while playing other games.
The business model is very comprehensive. They have a "wish" system. You can do account upgrades or character upgrades for wishes. Wishes can be either bought or earned. (For example, if you refer others to the game, you get a percentage of wish for every wish they buy.) The purchases can be astetic, such as changing your chat color or getting an icon next to your name, or functional, such as increasing inventory and collection capacities. In additon, there are "ease of use" upgrades that are intersting, such as allowing you to type in longer messages in chat (you are initially limited to 50 characters) or making it so you can join a guild. Anyhow, this specific one has held my insterest for longer than others, so I figured I'd share. If you're interested, you can check it out (and hook me up) by using this link http://www.DomainOfHeroes.com/?rpid=60267 . If you do choose to try it, I suggest reading the quick start guide before you dig in, it is fairly short, and you'll be better off for it.
