Good question, ZloDeySan. Yes, the game is developing in my opinion. Before I continue typing this out I think that I need to explain my motivations. So, I am a forum moderator, that just means I make sure that people are being polite and following the rules on the Forum. My relationship with Kingdoms and it's development does not go any further than that. I am a player first.
Onto my opinion on if I think the game is developing...
YES! Travian has always been a slow roll. I look at the development of Travian Legends. I started playing there in 2007. It was 2011 when they finally came out with the updated hero and the auction house. Looking backwards - it seems like those two events happened back-to-back, but there was at least 4 years between the two.
Kingdoms came out in 2015. It kind of feels like we've always had the Menhir feature, but there was over 3 years where we didn't have that feature. It wasn't available until October of 2018.
We like our x5 servers, but those are relatively new as well. I remember when they tested the first x5 server... it was less than enjoyable to play! That first day - nothing happened - nothing could happen. I remember my hero couldn't come home. It was a frustrating experience, but I look at the x5 servers today and they run very smoothly.
The app this year saw an update. Just a year ago, my first server playing King, Com2nx3, I couldn't use the app. It was impossible. I couldn't open the messages without it completely collapsing. This most recent update has made it so much easier to operate through the app. There are still some issues - like for me the app crashes every single time I set up a new trade route. A minor inconvenience when compared to how it used to work. They are even still updating these apps as new issues are found. This is great progress in my eyes.
The expanded warehouses on x3 and x5 are brand new! I was thrilled with it showing up on US and EU Birthday Bash servers. Right now the new changes that might come out of the Test round regarding Menhiring and Vacation Mode are promising. Vacation Mode genuinely benefits players that I've been around, but I'm happy to see an update that prevents the most recent exploitation of it that doesn't hurt governors who actually use it.
This doesn't include the changes to the achievement system (which is another main reason I enjoy Kingdoms over Legends in addition to the app).
The x3n servers are also new. Night truce has been around for awhile (2017, I think?), but the x3 tilt is new. I love the x3n servers. They're a lot of fun, but I don't think it's a fair assessment to say there is nothing new in the game because those don't run more than 1 time a year.
I love this game. I'm happy with how it has evolved over the years. As a player - there have been countless times that I've been frustrated with the functionality of the game. I've been in the Help Center writing up tickets more than just about anyone. On Com2nx3 when you merged Kingdoms, the Vice-King's treasury just stopped working. They lost all influence. That was another really frustrating day.
I'm glad to say that the issues that I've run into over the years have been resolved in future rounds. The Help Center at times has been slow when I report things, but ultimately a resolution is reached and the problems that I've encountered haven't reappeared on future rounds - and I consider that a win.
This isn't an exhaustive list about what all has changed in the game recently, but of the features that I as a player have been most excited about. As I said in my last post: Kingdoms today is also a lot different than it was when it first came out. It has continued to evolve since it was first launched - and I anticipate that the game will continue to be expanded and improved with time - I'm excited to see what the future brings.
