FFXI, original mmorpg.

User Rating: 10 | Final Fantasy XI PC
I agree with many people that this game is kind of hard and challenging. But that is the point why it's fun! I've experienced mmorpg's like WoW, Lineage II, Guild Wars, RO, etc. so I can find out the differences. FFXI is a bit old but it is not outdated, its graphics is still in the top range and the game is just getting better. This mmorpg is unlike other mmorpg where you can just solo almost to the max level, this game actually wants you to party with other players in order to do tons of quests, battles, and leveling. That is why I choose this as the best (in my own opinion) mmorpg. If you can just do everything by yourself, then why don't you just get an offline game, which is much better in everything. The game story is extremely well put, it's just like a movie, but just put it into a in-game version. Besides leveling, game missions and storyline are what worth playing too.

As for language problem, it's actually not a big deal. In my friend list, almost all Japanese understand English, and as for those who don't know English well, FFXI has a translation system which they use pretty well.

Now the game is at a really reasonable price.
If you look for long, enjoyable mmorpg, get this.
If you look for fast-soloing mmorpg, consider other mmorpg's.
