As I mentioned earlier, DOTA 2 has become a hit because it is very competitive. When I first started playing, there were only a few people playing it in my area, but now I can't walk in the door without seeing someone playing it in the basement or in some corner. It's gotten so popular that there is even an instructional video that can show you all of the basic tips that you need to know in order to be a successful player. The best part is that the developers have made it completely user friendly for newcomers. There is no complicated set of commands that you need to follow in order to be successful.
