Im not the best at reviewing something but i can try..
You can buy acclaim coins with real money, with those coins you can buy items from their shop. 20% Extra exp from every monster is one item. HP and MP Pots is another + alot more.
Now, i've played the game quite abit last month or so, Level 81....BUT i've been 81 for over a week now, i just can't find the effort to grind any longer...
Skills are nice, Weapons and Armours nice aswell, PvP is OKAY..It's not the best
You can be basically killed by anyone / level outside of town while your grinding/leveling. If they try killing you their name goes purple IF you don't attack them and they kill you they turn red for some amount of time and anyone can kill them without going purple or red.
It certainly is a MMORPG. Theres npcs quests armour weapons farming in some sense at higher levels.
From my personal knowledge and experience of the game I'd recommend for anyone to TRY it. You might love it or you might hate it. But its one of the best MMORPG out there.
