Owl-kin could be cool down the line.
But I agree with @Roccandil , just dark screen will not help, because today GPUs and monitors have good way of altering brightness levels by hardware, so this is not something that cheat engines can detect. It is a simple modification of brightness and gamma on players hardware.
So in addition to having a dark screen, I would agree that having other players characters not rendering unless you can actually see them would be very nice, so altering your monitors brightness would still not help you in PvP, and in PvE as well if mobs follow same rendering principles.
Torch, PER, and innate racial night vision could be some of the factors that affect on how other characters and mobs render around you and at what distance.
Rendering distance:
- not rendering at all
- close
- medium
- distant
Character transparency:
- invisible
- very transparent (barely visible)
- half transparent (averagely visible)
- not transparent (fully rendered)
Combination of rendering distance, and character transparency, based on various factors (torches, PER, innate night vision, tech, etc.) would be pretty cool. Of course, it would require some extra development work.
But think about it:
-
using torch and having no night vision = characters render only at distance that torch lights up (perhaps there are stronger and weaker torches)
-
using torch and having night vision, low PER = characters in torch light radius render fully, characters outside of torch radius are half transparent
-
using torch, having night vision AND high PER = characters outside of torch light radius render with almost no transparency (better visible)
-
having night vision, high PER, but no torch = characters inside closer radius, aren't rendered fully, but are rendered same as outside of torch radius, partly transparent, depending on PER
-
high PER, no torch, no night vision = characters in close radius are rendered half transparent, characters at longer distances are barely visible (strong transparency, only some blurry edges are periodically visible, then vanish)
-
low PER, no night vision, no torch = you don't see characters rendered even at close range (just feel that dagger stabbing you from behind)
Include other factors like tech, perhaps characters being tired, thirsty, hungry, etc. and you can get huge amount of combinations. I would personally love to see something like that.
Again I acknowledge, as awesome as it would sound, it would be a lots of development work.
