Konami's classic Castlevania: Symphony of the Night originally for the Sony PlayStation is packed with all kind of small details and nice touches that are very easy to miss if you're blasting through the game at top speed. Take some time to explore the haunted castle and really soak in the atmosphere. VGJUNK has a list of little moments and quirky additions in Symphony that you may have missed if you weren't paying attention. For instance, are you familiar with the list of field notes for each monster you'll find in the castle?
As is customary amongst lords of the night, Dracula's castle is packed with a menagerie of monstrous creatures including, but not limited to: bats, larger bats, skeletons, larger skeletons, ninja skeletons, demonic puppets from Hell, Great Old Ones, angry tables and, in the Sega Saturn version, something called the Human Face Tree, which is even creepier than it sounds. Once you've killed a monster, its information is added to the game's bestiary for you to peruse at your leisure, and I suggest that you do so because Symphony of the Night's monster list is an absolute joy to read.
Just take a moment to bask in the glorious phrase "specially trained war-goose." Not one of your regular war geese, oh no, it's one that been specially trained. Nothing but the best for Dracula's castle. It makes sense that a goose would be chosen for this military role, because geese are the most naturally aggressive and remorseless birds on the Earth.
Symphony and its sequels are full of these kinds of things, although you can tell that this game was especially crafted with love, creativity, and care. This is a game where a vampire flicks peanuts into his mouth to restore health, where skeletons run away in delight when you slay their slavedriver master, and there's an optional shoe item that makes Alucard one pixel taller as its sole function. Keep an eye out when you're stabbing demons and jumping across platforms. You just might be entertained in the middle of all of that entertainment. It's an absolute creative crime that Konami no longer makes games like this one.
