I've been playing this game for over a year and a half now and it's one of my all time favourites. There are lots of updates with new skills or materials, different game styles such as Iron Cow players, and lots of guilds for different players. My only criticism would be the lack of support for guild leaders, such as not being able to see when players were last online and not being able to sort members in any way ; I have to keep a spreadsheet of all my players levels.
