Yes it is low on PC (2000 playing on PC as of this post): http://swbstats.com/
Then this is precisely the right time to start with the first one for me.
This game is based so much on level weapon unlocks, that playing on a populated server as a rookie will just get me killed over and over until I quit in frustration. Playing with a small number of new players should make the game slower, but more enjoyable for all.
Also, did not buy the first one at full price, not buying the next one at full price either.
I just got this now because I got $120 (on launch price) value for $10.
