You actually see it alot in some supposedly dumb games implemented on a primitive level. In shooters whether FPS such as F.E.A.R (especially 3 as Paxton Fettle) or something else like Renegade Ops, Stealth games generally but in an exaggerated example "Not the Robots", Din Curse, Creeper World (series) Skyward Collapse, Jagged Alliance,. You are working with completely different toolkits to often completely different aims.
