Why would you play browser based games?
Browser based games are games that do not require any kind of downloads.
They are fun, most of them are interactive games which means that you will have to communicate with other people.
What you need to have is an internet connection and web browser. In communication, I mean by dealing or trading with others, killing them or even chatting with them in chat rooms or forums. Browser based games are fun to play. It is a great way to kill your time. They work on all types of computers and they do not require any high specifications. You can play them as long as your PC runs web browsers.

There are a few different types of browser based games you can choose to play. Most common games are Role Playing Games (RPG) where you take a role of one character (in some games, you can control a several characters) and you build him/her stronger.
Basically, you train, you fight monsters and level up and increase their statistics and powers. The other one is strategy games. They are really fun as you can control the whole army and send them to war or you can grow plants and take care of your garden.

There are plenty of sub-categories for this one. There are many other types of browser based games but it would be too long and boring to read. There are plenty of them though most of them use the same kind of script which was played and done several times. It is a little bit harder to find unique browser based games to play.

The other important thing about these kind of browser based games is to know whether you want a short time consuming game or long time consuming game. Short time consuming games won't consume much time as you probably need to play like ten to one hour per day and you still can compete with other people. Some of them are boring while most of them are not boring though you can play a few games at the time. Unlike time consuming games, you have to spend hours and hours if you want to compete with champion or top players. They also become boring as you keep playing unlike low time consuming browser based games. You do not sit there hours to level up or complete the quest, you simply spend your energy and go away.

In conclusion, I must say that browser based games are really good and fun games if you do not play a game hours and hours as it gets bored unless it is really good and long game. However, really long games most likely are playable with paid subscription which costs money. If you do not want to spend money or time on fun games, look for low time consuming browser based games. There are plenty of them.
