Tagoria

Tagoria is quite an interesting browser-based multiplayer role-playing online game. In the game, you play as a character in the land of Tagoria. You can gain experience and level up by 2 means: by doing PvP and by killing monsters. Besides simply level up, you can buy training points - which are assigned to Strength, Dexterity, Agility, Stamina, Accuracy - by using amber stones which is the currency in Tagoria.

In the beginning, you would probably like to gain experience and amber stone by killing other players. As the premium feature is available for free for the first few days of playing, you can easily choose players that are weaker than you to kill. After killing a few players, you have gained a level and owned some amber stone to buy training point, you can start doing quests and kill monsters in the Mountain.

You got a number of action points and quest points everyday, so you would probably just need to play 15-30 minutes a day. Tagoria would be quite a leisure game which would not need a lot of intensive care and attention like most of other online games. Tagoria would be suitable for you if you are a leisure player.

One nice feature of the game is you are able to work in a Farm, so that you can gain amber stones automatically while you are offline.
