1. Developers' Attention To Feedback
If there's one thing with which the Information Age has blessed us, it's the fact that patching content in digital media is, now, the norm. Although some game developers still refuse to look at their games during their time of need, developers of MOBAs and Fighters have a reputation of listening to the players when it comes to the game. These developers want their games to be the next big eSport and can't afford to let an imbalance of power continue to exist in the competitive universe. I know that League of Legends players are thankful that they don't have to deal with what you'll see in the video below anymore, and it's because the developer was alerted that the character was too strong; so, his power was reduced accordingly. https://www.youtube.com/watch?v=CHw1_Csup84 These games go through all sorts of changes; some changes are much more than just balance changes, however. Some even see the need to re-release the game in order to pack all of their largest changes into one complete package. These are the things that keep these games at the top of the charts in terms of playability and integrity and are still able to keep their players loyal to their games. Not everybody will see it (even after reading this), but these games are actually more closely related than they may realize. The developers all seem to have the same goals in mind when they make these games, and I think it's amazing that two completely different genres of games that were created in distinctively different time periods in gaming history can actually prove to be very similar and, together, have such a great impact on bringing a new respect for the video game community and video games, as an activity.
