I don't usually write in this forum as I don't visit this game as often and i never got too deep into it before the latest world which improved amazing changes in my opinion, and i was happy to see how often new updates were out, even if most of them were combat related in a game which i don't personally enjoy focusing on that, or even building cities or forming alliances.
I've come to realize how much i care about the future of h&h, this game is like non others and each time i started playing it again i learned more and more and my experience each time was dramatically different, and i absolutely loved it.
There are two main reasons that I'm writing this, one is because of the recent announcement of a new world and a new payment system, and one is because i always preferred to play this game alone, I enjoyed socializing with the few nice people I met in the game (not saying people aren't nice, just saying i don't see many people :p ) But ultimately me and some other people still prefer to play as a hermit.
More than that, It could actually benefit new players to play alone, as they can experience and learn more about the game when they're not surrounded by trees which all of their materials have been taken already, not to start about finding rocks (even though the ability to dig rocks from the ground is a fantastic idea and it possibly fixed that, so well done on that).
This is why i suggest the following:
Let new players who haven't paid play for unlimited time on a single player client, and if they want to join the real fun, on the MMO server, they'll have to get verified, or even pay monthly.
Playing alone as a new player and learning the ropes could get you anticipation towards playing with more people, and will give people a reason to pay for the game, and they wont be so confused when they go in to the game which could help bring some more players who couldn't understand the game (because to be honest with you guys, this game sure is confusing :d )
But now there are a few ways this can branch out and i leave this discussion to the rest of the community and the devs,
First off, should you allow non verified accounts to play online? you could still give them 7 hours a week, but I would suggest instead to give them 24 hours as a start, and then if they want to continue they have to pay. In a way, this will do exactly what the limitations on stats would do, so I think it's a good substitute.
Second, are verified accounts going to have limitations? because otherwise it makes subscriptions absolute, and you'll probably have to increase the cost of verifying an account. Still i think that if you put limitations on verified (non subscribed) players it shouldn't be on the in game progression and character developing, whenever my character gets stronger and becomes able to do more things i learn more about the game and new possibilities are created, if you'll stop that then at some point the game would feel too dull.
My personal ideal solution would be, if a single player client could be made, to keep the 14 hours a week system, in my opinion it's perfectly enough for people who play casually or don't care that much about being in the top tier of players, this way if they want to play the game for unlimited time, they can still keep a single player character going. And if someone cares that much about the game they could pay for a few months and play as much as they like, just like the current system, But that's open to discussion.
Anyway I don't get many times to say this but this game is absolutely awesome and very creative, so thanks for creating it and working hard on making it better. Good luck!
