I would consider this game very tame, especially since the game basically revolves around 1-VS-1 combat. There is no real gore, the language is appropriate for most ages, and the ability to play this game is available to anybody. No special talents are needed to be learned while playing this game- it's just a "pick up and play" game. A very important positive factor in this game is the good security on all online interactions. If the online interactions were under any less control, I would say you should be 13 years and up to play this- but because it is well manage, I say being 10 is the appropriate age.

This is great if you want a good brawler with 30+ characters that's portable.
