The best of World of Warcraft and Ragnarok Online blended together into a great MMORPG.
The environment itself is beautiful to look at. You'll notice small things such as butterflys, birds, fireflys as well as day and night cycles that rotate on a 30 min or so basis. At night, players will notice stars,nebulas and other planets lighting up the sky. The character and monster models also look great, but they do look a bit childish and may deter some people who prefer darker MMOs like World of Warcraft or Guild Wars, but they still look amazing and shouldn't deter you from the great gamplay.
The music and backgound noise in the game are both nice touches added to the game. There are a lot of sound effect's used for various weapons, monster attacks, skills etc. as well as for different surfaces as you walk over them. However, some voices in NPCs would be a much welcome addition.
Now you can download this game of the website for free, and the file is not that big, at around 400-500 mbs, but like most MMORPGs, there is a monthly fee you do have to pay, and it is a bit pricy with ROSe Online at around $15 a month, but you can try to find a private server to play on if you want to but if you can spare $15 a month, its $15 well spent.
Now for anybody who either is new to MMORPGs or is familiar with the genre should definately play this game as it would be a great experience.
