I played L2 US servers for about half a year, from Open Beta to C1 or so, i gotta say it's a grind game. It was very fun until certain factors completely changed the game

1. Gold Farmers, like every other MMO,s this game has it's share of Gold farmers from china, even more because the game is really based on adena (ingame gold) Adena can buy you literally almost everything.

2. The grind is very steep. Unless you are getting power lvled, it'll take you months to lvl up.

3. The right class is crucial. Don't expect this to be WoW where every class has an equal opportunity. Healers are healers and will remain as healers.

4. It's a partying game. Soloing has it's limits.

5. It's a PVP centered game. If you love to pvp, love to have the risk of pvp, love to be a pain to someone you hate.. love to hunt down that particular someone just ot kill him. THen this game is for you. Not for the weak i gotta say.

6. Clan wars, castle sieges, Awesome experience. If you do grind and become one of the elites in the server, be in an awesome guild where you have almost hundred members.. be prepare to experience awesome clan wars and castle sieges. I participated in multiple clan sieges. It's an awesome experience that no other game (online or offline) ever gave me before.

7. I only played till C1, never played after that.. i'm sure the latest interlude which introduces a brand new race would be even better. but that depends if we're getting it here..
