Is this game still worth getting into again?

[Penthea]

The game is far from dead. Players have just moved on to hanging around in different cities and doing different content, which is normal when new expansions are released.

Next question would be, in the case the ppl are still here but doing something else, whats going on nowadays? Is it only a static group grind for the newest gear where everyone only logs in once per week to get it or hows the current gamestyle?

There is no single answer for this. I could answer this in four different ways based on the behaviour of just my fc members.

A better question would be to ask about content you're interested in doing (raiding, pvp, etc) and then people could give you their opinions on how that section of the game is doing.
