Some of the online games might have something to make you take a lot of time and money to play it.
I used to play online games,and be addict to it,so,don't play them.
You also need a lot of time to learn it,isn't it?

Online learning is very good. I have been using online learning since I left senior high school. The advantage of online learning is that it can make you study at home instead of studying at some other places or suburban areas. Secondly, the curriculum of online learning is flexible. You can have lessons whenever you can. Finally, it is also a free learning environment. That is why I like online learning.
