The ratings suck. Tera 3/5 where worse mmo's score 4/5 or even 5/5? Please. Guild Wars 2 has a great art direction? No mention of Tera's art? Tera's art is waaay better than Guild Wars 2. Just look at the flora and landscapes. Must say though, Planetside 2 does look interesting.
Wither you love or hate it. How are you gonna give the most popular a 4/5. WoW is still the king wither you want to admit it or not. Thus deserves the highest rating.
And then you go on and give lotr/swtor (which I did like) a 4/5. They really should have at most 3/5. That's being generous to lotr.
Planetside is really one of the few that I can agree on. As for what it is I think it hit the nail right on the head.
