I'd say this game is overtalked about, not overplayed. There are ways to get your lvl up faster, when I have more time I'll gve you some pointers when I get back.
There was a thread about this a while back, but i don't have time to find it for you until later today. Try searching the Off topic and chitchat sections.
Dude, Im at a lvl 50. The game is addicting. I remember someone posting that they had 170 hours played on it and i have 92. But any game that you find very intresting you are going to play alot. If your only a lvl 5 and you want to get it up jus look at what your major skills are and work on using them wherever you go, thats what i did.
The game is really addicting, I had to stop myself from playing it so I poped in Halo 2 lol, Im almost done getting everything to 100 after that there is prabably 30 quests and im done...
