Hey! First, let me say that I really like the game so far. It's really fun. I don't really like the energy-based playtime limit in general, but I understand why it's implemented. That's not the problem.
The problem is that... mist energy is shared between different accounts, at least on the same computer/IP. I could understand this making sense if everyone used their own computer, but tons of people share. My girlfriend and I both play video games. We were both interested in Spiral Knights, and were excited that we get to finally play; however, when my girlfriend got home from work yesterday, we were horrified to find out that the energy was shared, and I had already used most of it up, severely limiting her enjoyment because she had to stop so soon after the tutorial.
We both spend real money on free online games fairly often, and I understand that doing so will make this stop, but we prefer to wait until we can thoroughly play around with the game otherwise, and we're not really able to do so in a decent amount of time if we have to share energy.
There is a thread about this already here: http://forums.spiralknights.com/node/1775 A lot of the cons of sharing are stated there
And I'm sure this has been discussed to death in the past.
However
I have to agree here, this is the one big oversight with sharing Mist Energy. If you have more than one person that wants to play in a household. It's a pretty big pain in the neck, especially if the solutions here are to
A) share one knight amongst everyone
B) have multiple knights that compete for the mist energy
C) pay for extra just to be able to play (you'd have to pay what $3 a week to get the 700 energy that the other knight gets for free, I mean I know that sounds petty, you could just not buy a coffee for the week or something, but when others are getting that 700 for free it's a bit annoying)
D) buy a new computer? going to a Starbucks and playing?
There must be a reasonable solution to multiple people on the same computer wanting to play that also doesn't compromise gameplay.
