If there is one certain thing in this world, it is that people always go on the easy way. When it comes to game category like fighting games, people tend to play MOBAs and FPSes games rather than the fighting games. This is because fighting games are quite hard to learn, master and execute. For example, DOTA has a wide variety of skills and spectrum that players need to learn before battling competitively in the gaming community. It has an MMR that ranges from 0k to 9k and is continuously increasing its skill level. In my own opinion, MOBAs and FPSes are quite easier to play and contain fewer challenges compared to the biggest fighting games online. Hence, it is one of the reasons why fighting games are not as popular as such games.
Even though Counter-Strike Offensive, which is an example of FPS has wide various and several game modes that include demolition, competitive and casual modes, this game tends to attract lesser skilled games. Moreover, according to some reviews, Demolition mode in Counter-Strike Offensive Global has simpler and more relaxed team kill and rules compared to other fighting games.
In addition, fighting games usually function on a 2 dimensional frame, which makes a big turn off for fanatic gamers. Some fighting moves in fighting games usually require full circle inputs and a ton of buttons that players need to properly execute. As people go with traditional setting of MOBAS and FPS, it is undeniable that these gamers tend to go on the easier part of gaming. However, for people who want challenge and intense gaming, fighting games like dominoqq are the best game category for them. After all, gaming is a competitive platform in our generation nowadays.
