This game has another interesting revenue model, in that you can buy the game and play it for free forever, but you have the option of buying premium status which increases your XP gain and daily Grace on login. The higher tier premium options include Plot Tokens which allow you to own and maintain one plot of land per token for one month. The game also allows you to own one Grace Plot which is paid entirely using Grace.
I play that game. It's literally buy to play. You also get a plot per month you can easily earn in game.
Here's another Wurm Online:
Small sub (otherwise capped). If your sub runs out crafting and such is brought down to irrelevant levels however you retain the ability to sail ships, ride horses, ride carts etc.
Then all the money in game, even when you get it from game actions is bought by players. Allows some people with little time to buy money (for deeds trade, etc). Allows others to earn it through grind.
Sounds very P2W right? Well it works. A lot of people wouldn't have been playing if this wasn't an option. Also earning money has some weight to it.
MO2? I'd like the option to be able to login and keep my stuff when I'm not actively playing, or just look around. RIght now I have a sub for playing once per mon th. But then again it's an honest monetization. The old pay sub play game from my childhood (except runescape which allowed you to play free to a point).
