Pause to screen: You can put the entire world on pause at will, but your body will also freeze along with others, with only your mind remaining active to think and resume back time.
Respawn on death: Upon dying against your will, you will be presented with an option of respawning back to your bed or any familiar safespace, and an option to confirm your death.
Rapid health regeneration: Your body will quickly heal after sudden injury to full health when left undamaged for a minute.
Built in HUD: You will be able to view your body's stats directly within your vision, like meters/numbers for any type of body metric, your inventory, a minimap and reminders/alerts.
Skill Tree: You level up on your birthdays and acquire a skill point to spend on various types of stats and powers of your choice.
Fast travel: You can instantly teleport to your personally known safe places, no matter how far away they are, except in situations where you are busy and not allowed to leave the vicinity. (By courtesy of ChrisFhey)
Skill Check: While doing an action, you will be able to observe if you have the necessary stats required to perform that action successfully. (By courtesy of nieceandtows)
Note: Save/Load has been intentionally left out since it is essentially more OP than all of the other options listed here.
Edit: changed title from 'superpower' to 'game feature' + misspellings + 6th and 7th point
HUD would be a great feature. Apart from save/load, another feature I would really love is the success percentage for various actions, like in the fallout games. If I can see what I’ll get for my different comments, I’ll know when to shut my mouth.
Save/Load. Because it is the most OP and basically negates most of the suggestions given. It's effectively time travel, assuming I also retain knowledge of a previously "played game."
And if I'm not allowed that... Modding. So I can add that feature back in. :P
This was a tough pic between Skill Tree and Built in HUD, but I'm going with Skill Tree, it seems the most useful in my opinion. It would be cool to know what's going on with your body when you feel funny though
Certain movements making you invincible for a moment, like sitting/standing up animations from old 3d games. I don't say this because I tripped after sitting on a bench for too long.
yeah, it's very ingeniously limited, although i kind of take an issue with the specific consequence posited in the ending. subtracting that, i think it would be somewhat OP, but not more than rapid health regen or respawn.
life is strange spoilers, DO NOT OPEN IF YOU HAVEN'T PLAYED THE GAME. seriously, it's an amazing experience, don't rob yourself of this one.
you opened it. don't. go back. seriously.
Kate kills Victoria.
alright.
if you're still here, i guess you have played, and you also likely know that's bullshit, lol. let's get serious.
so the game tries to tell us in ep5 that Max is responsible for the storm, and that going back and not using her powers to save Chloe is going to stop causing that. but honestly, that theory is propped up by a ridiculous amount of one-off rules:
when Max saves William, she somehow brings the storm with herself to that timeline (the bathroom scene does not happen in this timeline for obvious reasons but the storm is still coming). however, she doesn't bring it with herself to the bay ending timeline, even though she enters that one the same way.
whether Chloe is alive or not is posited to have an effect on the storm but the same is not true for Kate
Max gets a vision of the storm before she "created" it by saving Chloe
she also rewinds three times before taking the butterfly pic, which apparently don't cause a storm
if the problem is deviation from the "original" timeline (which is weird, how does the universe remember what's original and what's not?) why does the deviation only create a storm 5 years later when saving William, but arrive in only 5 days, on the exact same day, when saving Chloe?
in the end, so many rules and explanations have to be fridged for this to work that there are only two logical explanations: that there is an intelligent universe that just has it out for Chloe, or that Max didn't create the storm. she isn't the only thing that's supernatural and weird about arcadia bay, so while she clearly can stop the storm by some miracle, it's very unlikely that she put it in place.
therefore, if we are to consider the consequences of one of us gaining the rewind,
if the universe just has it out for Chloe, we're safe, unless we meet Chloe
if Max didn't create the storm, we're safe, we won't create storms
that said, i doubt i'd use the photo-jump much. you can lose so much to the effects of chaos theory -- and i'm not talking supernatural storms, i'm talking very natural things in your life not happening.
