I've had this game for about a week. I used to be an avid Battle of the Immortals player (BoI was a prequel to WoI) and I was unamused that the games are almost identical, but WoI has a few more features. It is still a decent game, but it is extremely pay to win, as all Perfect World games are. If you get to know the company, you will realize that they are only determined to receive money and have no care for their players.
+Quests and dungeons alike
+Can be decently played without donating (why would you?), but can be hard later on
+Sick glowing gears
+Intricate pet system (2nd best - Rappelz has the best pet system known to date IMO.)
-Almost identical to its predecessors
-Very repetitive later on
-Can be boring later on
-Pay to win increases drastically after level 85-90
-THE WORST customer support. Period.
-Energy and purchasing are required to use world chat / server chat
-Nobody to play with at lower levels, thankfully it's easy to solo up to about 90
Graphics: 4/10 (If it was 3D I'd be impressed.)
Addiction/Lasting Appeal: 4.5/10
Pay to win: 9.5/10
Meh. I'd recommend it for those who want a laid back MMO. This game gives you all you need and then some for just leveling.
