In-game collectibles have become a mainstay of modern gaming. Almost every title that comes out features a variety of optional hidden items littering the world players have to seek out. While they are rarely an essential part of the story, they can add extra enjoyment to the overall experience if done right.
The very best collectibles are expertly hidden to encourage exploration and come along with a system designed to help the player keep track of what they still need to find. They also tend to provide some tangible benefit, whether it be extra powers, additional lore, or ridiculous cheat codes. It's no coincidence many of the most addictive video games ever contain a slew of fun goodies to search out.
The world of Skyrim is massive; there's so much to explore and uncover collectibles in the traditional sense aren't really necessary. What the RPG does have is a collection of Daedric artifacts that can only be acquired in very particular ways. Hidden throughout the game world are a series of Daedric altars where demonic creatures offer the player short quests in exchange for powerful items.
These items range from weapons to armor, and all have unique abilities that make them stand out from the game's normal loot. Collecting them all means traveling into a literal world of nightmares, piecing together a very drunk night, and filling a role in a bizarre Alice In Wonderland style adventure.
This last endeavor nabs you the Wabbajack, which is arguably the most powerful weapon in the game; it can transform any enemy into a non-threatening animal like a rabbit or chicken, make your opponent explode in a burst of flames, or morph them into a sinister and deadly Dremora Lord. The only catch is the specific effect is totally random.
Bethesda did their best to make the collectibles in Fallout 3 as fun to find as possible. When the game world is huge, it's important to encourage players to go out and explore in a way that doesn’t feel too forced. The bobbleheads are an excellent solution to this conundrum.
These little figures are hidden away in interesting locations you might not necessarily visit otherwise. Once found, they can be displayed at your in-game home and each provides a permanent skill boost that's extremely difficult to gain any other way, making them both valuable and rewarding.
Generally speaking, first-person shooters are focused on fast-paced action, so taking time to slow down and search for collectibles goes against the grain. When shooters do include them, they often feel tacked on, like the hidden bags in Mirror's Edge that don't actually give the player anything new.
The Halo series is a bit different. The vast majority of Halo games include a set of hidden skulls stashed away in tricky to reach places. They often require the player to do specific actions before they show up on the map, such as jumping through a set of rings in a particular order.
Even though each game only features about a dozen, all are very rewarding to find. By getting players to experiment with the gameplay mechanics and exploit "broken" parts of the world, Bungie made collecting the skulls incredibly fun. On top of that, each skull unlocks a new gameplay variant ranging from difficulty boosters like the Iron Skull, which eliminates mid-mission checkpoints, to goofy Easter eggs like the Grunt Birthday Party Skull, which makes weaker enemies explode in bursts of confetti when you shoot them in the head.
Super Mario Odyssey is well aware of how enjoyable it is to collect things. For the first real Mario game on the Switch, Nintendo packed the world full of more treasure than ever before. On top of a slew of unique costumes, regional purple coins, and regular gold coins, there's 999 Power Moons (roughly 10 times as many as past Mario games) to hunt down.
The player only needs a fraction of these moons to reach the end of the story, meaning there are plenty of optional moons to collect, and they are everywhere. Early in the game, it's pretty normal to be unlocking a new moon every few minutes, leading to a near-endless cycle of satisfaction. For dedicated players, there are tons of cool unlockables tied to collecting extra moons, including brand new levels.
