Obviously 52, 80 or even the 150 players that were online at peak times aren\'t \"many\" by standards of finished MMORPGs. Alas, they indeed are a lot by standards of a beta-test pre-alpha tech demo of an MMORPG, especially if you consider that the server has been highly unstable for several weeks, the NPC AI is down most of the time and the quests are few and not all functional. Furthermore, they are about the right amount of players for the world, as that is currently tiny.
In fact, this is a really good thing, since the percentage of RPers has increased (as the number of PLs has decreased) due to that. Most activity ingame is mining or RP now.
So if you are into RP, or know someone who is, it will likely be worthwhile to play PS. If not, then it won\'t.
PS is, due to it\'s nature, free to cater only to one, or a select few, types of players, which are RPers. This is another reason why the playerbase isn\'t so large as in other MMO\"RP\"Gs. The overall quality in terms of RP in PS is comparatively high due to that.
Please take into consideration that PS is strongly geared towards RP when deciding whether or not to download the PS client.
