Since it's the only MMORPG I ever found appealing, I'm considering playing Lineage II a bit. However, in many MMORPGs, sooner or later there comes a time when you can do nothing as an individual, since everything is aimed at larger groups; and I'm not willing to coordinate my already schedule with a bunch of strange people.
Is there enough content for me, as a single player?
If not, how many teammates would I need to actually enjoy playing?
