Will there be achievements in the game? and Will there be guild achievements?

Also is there any guild perks for joining a guild?

I don't know the answer to your questions but I do hope there isn't any WoW-like guild perks. I am a fan of WoW and many other MMO's(feel free to hate) but guild perks ruined the guild system in WoW. Instead of guilds being full of friends it became guilds grabbing as many people as possible to get all the perks and 95% of the members being there only for the perks.

Guild perks I don't know, but there are game achievements. I got many achievements for doing different quests, but I also got PvP achievements for killing a certain number of enemies classes. For example, I think the first achievement I got in PvP was the soccer slayer.

I also got the "slaughtered" achievement by trying to swim to the white-gold tower and got eaten by slaughterfish

Oooooh yes, there are achievements. Zillions and zillions of achievements http://esohead.com/achievements

I've never been a big fan of achievements for their own sake, but in this case they can provide a very useful guide for the completionist explorer type who wants to know if they're missing anything.

Thanks Srikandi =) /cheers
