Except the designers know the limitations well enough in advance, and the artistic vision has always had to stay within the restraints that practicality allows. SIF and GATs are intended to strictly distract. If anything, removing that stuff allows a greater focus on the scares and scenes.
Compromises to artistic vision happen all the time. Changes and adjustments occur on the fly because reality and artistry, many times, don’t jive. We literally had a house last year cut its primary monster because of vision and comfort issues. The 2010 HotY was, literally, the same house from the year prior only repainted a dull gray with bald people in tank tops. House of Horrors in 2012 was a fan favorite that year when it was designed in 30 days.
These challenges aren’t new to A&D.
