The basic tropes on which nearly all action games are based are as follows: fighting in an arena; fighting in an environment through which you can travel; and rescuing people or things. There are, of course, variations on these themes – but in effect, these are the cornerstones of the titles you seek.
Yet people who like to play action games have different preferences. Someone who likes Street Fighter may not like Mortal Kombat. Someone who likes Ben Ten Ultimate Alien games may not like either of the others.
The reason for this is the same reason why people like different kinds of films and books, despite their being only seven kinds of story in the world. Top dressing and personality account for much more of our tastes than the basic mechanics of the things we are doing or seeing. Otherwise we’d all like every dish ever cooked by anyone – because ultimately they are all some ingredients combined in a way that makes something edible.
Street Fighter, for example, appeals to people who like cartoonish action games. The violence in Street Fighter games is laughable (in a good way) – stretchy limbs, people appearing and disappearing all over the place: even a green monster that can turn himself electric. Mortal Kombat, on the other hand, is much more visceral and serious (indeed some might say nasty): with killer moves designed to actually kill the loser on screen.
Ben Ten Ultimate Alien games fall more into the category of Street Fighter than Mortal Kombat – and so are more suitable for younger players, who like the cartoon. Indeed, liking the cartoon is an excellent way (as noted at the start) of working out what action games you are likely to enjoy and which ones you should probably avoid. Given that the gameplay is roughly the same, go with the characters you love.
There are (also as noted) some variations on the basic action game themes. For instance, some Ben Ten Ultimate Alien games allow you to create your own monsters and even game levels. This is a habit first picked up by games programmed in the mid 1980s, originally racing games where you could specify the different parts of your craft. The idea quickly spread to action games, where you became able to pick different weapons and characteristics for your players – notably in Budokan, where you could train your player in different martial arts.
