Very Good Game , and cheap too.
Now some people hate this game because of this factor, but most of the skill's in this game(fishing,farming,firemaking,woodcutting combat to name a few) revolve around clicking on a object again and again to level them up with the mouse (with the exception of a few).
The Combat system of this game is rather flawed, and the pvp part's of this game usually revolve around people who have build character's especially for pvp combat(called 'pures' by player's.)
For instance usually, it is not skill that is the main factor in combat, but rather the character's combat stat's(Attack,Defense,Strength,Magic,Ranged)
The Npc Character's you fight are numourous with many 'bosses' that are high level, hard to kill and yield very good loot.
I enjoy the 'slayer' skill, where you have to be a certain level to kill certain monster's, and as the slayer skill is rather hard to get to high level to kill the monster's that yield the best reward, if you are one of the few that do have a high level, rest assured you will be rewarded.
Although most people indulge in combat, the skill factor's of this game(Fishing,Mining,Smithing,Runecrafting etc.) are often chosen over combat,
but usually the money rate you get from skilling (even in high level's) is rather low, and can be outdone by 'merchanting' a technique of buying item's from other player's then then selling them for higher.
The community in this game are rather varied, but on the free world you will encounter many immature souls, and many scammer's so beware.
Overall, you should give this game a try, but be forewarned it is rather addictive, so remember it's only a game. You can either love this game, or hate it, and i love it, having been playing it(on and off) for 3 years.
