LoL vs HoN: In this article, we will be comparing two very popular MOBA games of all time. Both League of Legends and Heroes of Newerth have been around for almost around 10 years. Both the games are considered very addictive, but they are also considered very rewarding by certain audiences. However, LoL and HoN both offer a different variety of truly enjoyable experiences, and in this article, we will be comparing these 2 games.
Heroes of Newerth

Heroes of Newerth is a MOBA game developed by S2 Games. It is published by Frostburn Studios. HoN was inspired by Dota 1 and it tried its best to stay true to the original content. The game was released on May 12, 2010, and re-released as a free-to-play game on July 29, 2011.
About the gameplay however, HoN is a very competitive and punishing game. Specially for the new-comers. It is a very complex game and has a very steep learning curve. However, the game is very rewarding after you play for a certain amount of time, and get to understand the game.
League of Legends

Unlike HoN, League of Legends is beginner friendly game. The skill curve is not so steep, and even new players can enjoy the game after playing just a few matches.
LoL was released before HoN. Hence, League of Legends acquired a massive fanbase, before HoN could even begin the race. However, HoN was still quite popular and gave a good competition to League of Legends after its release.
Gameplay-wise, League removed many of the complicated gameplay elements from the original Dota, and made an interesting and welcoming game of a trending genre.
Conclusion
LoL vs HoN: Both Heroes of Newerth and League of Legends are incredible games. I think you should give them both a try. However, personally I am a huge HoN fan, and I think hardcore gamers would like HoN better than League.
