I started playing back in December '12, and around February one of the patches introduced a bug where the mouse input wasn't being read unless I played in windowed mode, so I waited for a bug fix and restarted playing once that came about. I'm also starting to run into players I saw around back at the start of the year coming back into the game again having taken a break from playing it.
As far as I'm concerned what I really like about this game, besides the gameplay itself, and what I think Muse has got 100% right, is the way the game encourages people to co-operate, rather than focusing on individual scores and beiing uber, even the most skillful players will lose unless they have both a working crew and a working team.
On top of that the long term player base is exceptional, I was in a match last night, tense, closely fought, despite vastly mixed player levels and length of in-game time played. In the post-game lobby all the players remarked on how enjoyable the game had been, best summed up by one of the other captains when he said "That's Guns of Icarus".
Yes there are matches from hell too, but it is really something special when there is that spark and sixteen or twenty four individuals suddenly gel.
If I have a few have reservations, it's about clans, having been in a few clans in my time and also played games where it was impossible to play without being in a clan, where the in-game culture was run along the lines of prison gangs, join up or expect to be continually beaten up and/or have all your stuff taken, so I hope implementation will be handled as well as the individual experience side of the game. That said I'm not criticising people who wish to be in clans, nor the existence of clans themselves, but simply clans just aren't for me.
