First of all I would like to say spiral knights is a great game. I really think the developers made it very well. It runs on linux and windows, has a nice 3d engine without too much resource usage, plays in a window, etc. The combat system is really good, with dodging, blocking, ranged and melee combat.
Second, I'd like to say this game has great value for money. Most of the mission and content are free. However at some point you will have to spend some money just to get your account validated and to get some energy. Still, the amount mandatory pay is low.
I just came back to spiral knights. I have not played for quite some time - months - perhaps even a year or so, I can't remember.
The first thing I notice is: Nothing has changed. I used to farm FSC, and this is still the best way to get crowns and heat. Energy did get more expensive, so farming is less lucrative. There are no new missions or content.
The only new thing are 'pets' and a new crafting system. After playing around for a day or two I find out that it has become much harder to level and craft your equipment. Am I glad I got most my stuff maxed out. The materials for forging don't drop as much as you need it. And it turns out you can now buy these in the energy depot.
At first I was excited to try out the new pets. Turns out I had to choose one, and buying another one is expensive. I spend a lot of time trying to figure out the one that was best for me. Then I started feeding it. After getting it to level 30 I realized I will never get it to level 100 to try the special abilities. Feeding it materials below 5 stars is just not worth it. I ran a lot of FSC runs, but heating a pet simply does not work, it only makes them hungry. It turns out these pets are meant to be a huge time and energy sink. Spiral knights is a fun little game, but I am not going to spend that much time on it just to level a virtual pet. After all, these are just some bits and bites.
Essentially they have added a bunch of new time- and energy gated content. At the same time they removed the 'free' daily energy. Looks like free play has been nerfed. I can understand why a company might want to nerf free play. But when I see no meaningful new content has been added in ages, it makes me frown.
So I could farm FSC for heat and materials, so I become more efficient at farming FSC, to farm more FSC, but I'm not going to do that. Overall I'd say spiral knights is still a great little game, and I hope some day it might actually be going somewhere (other than FSC). Maybe adding a few more rewarding missions and perhaps a couple more interesting bosses to add some variety.
Perhaps spiral knights became a little bit too demanding (and I am not talking about money here). Just my personal opinion.
Have a nice day everyone.
linux and windows
By the way, the game also runs on Mac OS X.
Most of the mission and content are free. However at some point you will have to spend some money just to get your account validated and to get some energy.
All of the missions and content are free. You do not ever need to spend money. (If you play through Steam, then you can even get Operation Crimson Hammer for free.) There are many players on this forum who have never spent money, but who have done all of the content, collected numerous 5-star items, etc. It's all free.
The first thing I notice is: Nothing has changed.
The 2013-07-30 update was the biggest update in Spiral Knights history (at least since launch). Many aspects of the game changed. But you are right that there have not been many new big features in the past year: Sprites, gorgonzola fiends, compounds, ...?
Looks like free play has been nerfed.
Somehow you have overlooked the fact that all elevators are now free. You can play this game as much as you want, all day long, without converting any of your hard-won crowns into energy to pay for elevators. This game is more free-to-play than ever.
Of course, I actually agree with you that Spiral Knights could use some new content. But I think that you're overstating the case.
