About halfway through this already worrying Kotaku article regarding The Witcher 3 is a section on Geralt’s “Witcher Vision”:
Witcher Vision is pretty cool. At any given moment, you can hold down a button to put Geralt’s field of vision into a sort of detective mode. This lets him see footprints, clues, key items, and the like. In practice, sleuthing around various environments—be they houses, dilapidated beach huts, or seemingly inconspicuous forests—isn’t very challenging, but it adds a lot to the feeling of being a Witcher.
All I could do was release a heavy sign and massage my temples.
“Detective vision” and its equivalents has never been good game design in any game I have ever played, for one specific reason: there is hardly any incentive to ever turn it off. Games with detective vision usually have hidden treasures and/or secret doors that are only visible in detective mode. This makes sense in a twisted-logic way, as why have detective vision at all if you can only use it in certain prescribed areas? That is basically “Press B to solve puzzle.” Of course, you don’t want to give players an ability that’s completely useless outside of specific zones either, for the same reason you don’t craft an elaborate cave complex with no treasure chest at the end. That’s just frustrating.
But the end result is that designers hide invisible things throughout the game because they feel they have to, and then the players end up spending the entire game with detective vision active so as to not miss these invisible things. Which means not only is nothing of use being accomplished (the actions cancel each other out), the player ends up spending the entire game in a sepia-colored wasteland devoid of all detail or immersion.
Case in point: Batman Arkham Asylum. Played and beat it a few months ago, but I couldn’t even really tell you how the game looked, because I was in X-Ray vision nearly the whole damn time. Case in point: Dishonored. The Dark Vision spell is an early upgrade that trivializes even the highest difficulty, no-kill runs. Beautiful game environments reduced to sepia-colored vomit for the whole rest of the game. Hell, I didn’t even like the scan mechanic all the way back in the first Metroid Prime game for these same reasons. I just ran around trying to scan every damn thing, just in case.
I honestly see no good solutions for this design issue. Even if you limit the player when they’re using detective vision (e.g. not letting them attack, or perhaps even move) that doesn’t stop players from feeling like they need to be utilizing it at every opportunity. Only allowing detective vision to be useable when there is something to detect is kinda asinine; why bother including it at all?
None of the solutions feel particularly good. One might think that the “search pulse” ability featured in Dragon Age: Inquisition, the original Witcher games, and many others might be better, but… I spend the whole damn game spamming those keys already. Same deal with the Battlefield series and PlanetSide 2, in spamming Q to spot enemies that I don’t actually see, but could be out there somewhere near my crosshairs. Sometimes it saves your life; there’s no reason not to.
This might well be one of those scenarios in which the “old school” solution of just making hidden things hard to find is best. At the same time, I don’t necessarily want to go back to the days of having to tab out and hit GameFAQs when I can’t find the pixels the designers wanted me to click on either. If I had to choose though, I would rather miss hidden treasure because I was too immersed in the game environment than miss it because I took a break from the otherwise permanent Instagram filters.
