Depends on your time zone. During weekdays, from 12PM to 18PM server time, server is at its busiest hours; from 0:00 AM to 6:00 AM it's kinda empty. Saturday night is when people play the most. There are about 80 to 120 people online at busy hours , so there is nothing to worry about.
Most of players live in Asia, so yea. You can check server time at top left corner to compare it with your time.
Have fun. See you in game.

Well the game aint really "dead" but its not like a proper retail server!
I suggest you get into a guild with people so you dont feel lonely too haha

So is it worth starting?
Does the game has proper PvE content and good PvP?
Or is it just a typical anime digest?

Plenty of content and I regularly develop more. The next update will have a new map and two new dungeons.
Check the front page and browse through the last few years of updates to get a picture

The PvE and PvP content are one of the best out there plus if NS gets so many players, it would be awesome.

I would be looking forward to that day.

Sedy is making me cry with happy tears looking at this new update. LOL
Suffice to say, this game has loaaaads of PvE content, raids parties and soloing
PvP is dependant on time cause there are times where the server seems to be much more quiet lol but its pretty frequent on end levels via Battlefield.

Field pvp though, not as much as before ^^

A bit of an off-topic -
The website is one of the best i saw. Ever.
I have a quesiton about signatures, how long does it take to change them? Does it go through staff approval? Because this signature took at least a few hours to actually work...

Thanks, I'm glad you like it
Signatures should show up instantly.
