Bought the 12 months straight up ...
This is what I have always wanted in EVE, played that since 2005 and love it and although I wasn't at the first release I watched it grow. Thats why I got the 12 month Perpetuum will grow and with it will be great changes except this time I caught it from close to the very beginning (had no clue about beta ).
Some people don't like it but I love the fact that I gain EP while out of the game it fits my lifestyle perfectly due to my work, and this lets me as far as character is concerned stay up there ... obviously others that are on all the time will have an advantage of finding new play styles and progressing in raw skill, but really at its current stage everything I know from massive fleet battles can pretty much work here too so that doesn't bother me ...
Maybe one thing that wasn't expected was an influx of people with knowledge of how to play a game like this and thats why we have seen some huge turns in alliances and allegiance and control, but hey it's all pretty exciting!
With continued support this game will grow ... either that or CCP will buy them out and link it to EVE LOL
