Oh man, if you are a fan of Streets of Rage, and hopefully sci-fi movies, then you will be right at home with the Neo Geo brawlers. They are not as good as the SoR games, but what is really, but they hold their own quite well. They are obviously quarter munchers but fun which is key for these types of games.
Just be prepared, most carry a sci-fi angle of some sort. There are a few, the Sengoku series, that are more ancient Chinese aesthetics, but for the most part, sci-fi. Fun times.
Will try those. Thanks.
