Blue Heat is a bit tacky as a game: I can't remember if it featured any sex scenes, but there certainly was nudity every 5 steps and it certainly didn't have the deepest or most sensible themes at times, however as far as gameplay goes, it's actually pretty good! You'll be checking alibis against the time of the murders and other similar comparisons to exclude people from your list of suspects as you try to figure out who's the culprit, and it succeeds in creating a reasonably challenging yet engaging investigation where most other games fail.
