Probably spent the most time this year playing Artificial before it started to slowly fade - really enjoyed it at the time.
I found that time is very lack lustre in my current work situation so I hopped on the HR bandwagon with Apoc V2 which is the first HR I've played since Mir Revenge.
Although I'm thoroughly enjoying Apoc at this stage, I have to give my vote to Artificial as they put together a great server and started out brilliantly, and purely as I've played more of it this year than any other server.
Also, no disrespect to Mir 3 but I tried it once many years ago, didn't like it.
