- mind control (solves a lot of headache problems, of other people)
(I wonder another power mentioned here is power of persuasion, but would mindcontrol be just a stronger version?)
- telephathy (this one is nice, always know what to do or say to get some girl into bed).
- invisibility (voyeur kink)
- growing bigger dick (separate wider or longer, always nice)
- shape shifting (I could play as others).
- timetravel, (difficulty I have here, is I want to be younger again, not my age, going back 30 years, that's just useless).
My presence having an aphrodisiac effect, or being able to terrorize people into letting me have my way (rape time! /joke ). Mind reading is great too, so you know exactly which buttons to push to gain affection or lust.
I also love having “real-life game mechanics”: a visible UI that quantifies the cost and benefit of every action (e.g., studying for 1 hour gives you 0.3 intellect), the ability to skip time, a pocket-dimension inventory to store your stuff. You know, the basics.
Time travel might seem redundant if you assume it’s just for rewinding choices (mind reading can achieve the same effect with less tedium). But hear me out: you time travel to access different ages of your love interest. Loli, young adult, MILF, you name it.
I wanna make machines and tools that could help elevate the whole experience to a point that you could easily make people see heaven through stimulation.
Put "solving humanity's problems" as an added bonus too.
Mind control for all the obvious reasons, it would prevent any headaches and you could live your harem fantasy.
However, the idea of time stop and all the chaos I could cause are tempting. Yes, I could mind control any and everyone to get and do what I want, but the idea of having my way with anyone and knocking them up with them none the wiser is peak. Imagining myself deflowering and impregnating local girls and everyone confused with where all of these pregnancies are coming from is top top-tier.
After typing this all out, I think I've talked myself into time stop.
A few of these wouldn't be ideal if they ever existed. Invisibility? You'd be blind because light would just pass through your retina. Time stop? You'd also be blind because light wouldn't actually travel but you'd also be unable to breathe because air wouldn't move.
Mind/will control would probably be my choice although, I guess that would come with its own complications and limitations. Teleportation would also be interesting; being able to go anywhere in an instant would be awesome; but that also would probably mean death if you can't create a vacuum right on the spot you're teleporting to..
