[1]as what I'm saying is simply how would someone earn with such games [2]and would it even such games be labeled nor include as one of 3D casino's the OP talks about or not[/b]. [3]And not all MMORPG games has no end, it's game makers only makes another version or a continuation if and only if their game went successful to the market.
[1] If you think MMORPG game doesn't make good money, creating a lot account and make the account become an farmer account will give you can earn some significant money if the game really had an active player, MMORPG or any game with a social activity like this when we have some market will be always have some farmer account. I'm already doing this and the money was really good but keep it mind you need a high level and spent so much time and the game have a good market so need to research about demand market. But the game has been mention by @OP when the grapich was really shit and not good at all, will never have a good market.
[2] About 3D Open World definition from @OP, I believe that's just a phrase from @OP to definition the type game. But he wrong or doesn't know to give the definition about the game, so just give some understanding about the @OP definition.
[3] That's for a game with no social trading item and will need to create another game version. every MMORPG game online let's say RanOnline or Dragonest when they already reach maximum level on their game they just can make some update for max level or open another Nest/Raid Dungeon. Well I pretty agree with the game about MMORPG was a game, but sometimes the developer and other things just want create something new into the market not only by seeing from most of game from casino.
Is this MMORPG game a lot of interest if the game is only adventurous then how to do the gambling. Honestly, I am still confused if there is gambling like this and no one has had success in this forum like this.
And it looks like this game is not as popular as other gambling sites, many people enjoy doing it.
Creating a system, when we have an option to put certainly money to Duel PVP Battle each character. But, off course a player with high spec, pay2win will be always a winners.
