X-Men Destiny a button mashing, fairly linear action game, but you do get to choose your powers and your allegiance so two play throughs are required if you want all the achievements and to see all the cut scenes and such. In the beginning you choose from one of three 
characters and one of three powers. As far as I can tell, character choice has no bearing on gameplay aside from the visual representation. The three powers you’re able to choose from are:
Energy projection: Shoot energy from hands
Shadow Matter: Control dark matter and manifest into solid form
Density control: Control the density of your body mass.
Since the game is called X-Men Destiny, you’re given some choices during the gameply on how your character progresses in regards to the powers they manifest (like a skill tree) what sort of X-Genes you equip (for added powers, effects) and some story elements and of course faction choice of X-Men or Brotherhood of Mutants.
They say there is some dialog selection, but it’s pretty basic, uninteresting stuff unless you want to see all manner of unnecessary chatting scenes with iconic Marvel mutants like Colossus, Quicksilver, Cycops, Emma Frost, Wolverine, etc.
Honestly, in the beginning I was going through every menu item in dialogs but quickly realized that it had no bearing on the gameplay. The major things that affect gameplay are which missions you take, gaining you faction points for one or the other and opening some challenge levels.
The thing I quite liked is that you don’t really have an inventory. Rather, you have a suit to choose from which comes with some special powers like faster healing in the case of the Wolverine suit. Some suits have no effect and are literally just cosmetic. The X-genes all have some effect on what you can do and these can be increased by spending XP on them.
There are three types of X-genes you can equip, defensive, offensive and utility. They’re all based on iconic X-Men comic characters and expand things like attack damage, armor, health, speed or M-power which is what allows you to pull off special moves from your Mutant Powers list.
