3 Games

1-Minecraft (Java Edition) https://www.minecraft.net/en-us 

    A 3D game based on breaking and placing blocks, with the eventual "Goal" of finding and defeating the Ender Dragon. Or messing around and building. Probably more the second one. -The basic controls of Minecraft are fairly simple, with your mouse controlling the direction your character faces, WASD controlling your movement, "E" being used to open your inventory, and Space to jump. (You can also modify how you move by using Shift to crouch and using either the control key or double tapping the "W" key to sprint.) 

    The inventory screen will contain any items you pick up, slots for armor, and a small 2x2 crafting grid that you can use to make simple items like wood planks or a crafting table. One of the first things you should do is get familiar with the movement keys above, then find a tree and get close enough to punch it. Holding down the left mouse button will let you mine blocks, with certain blocks like stone needing a pickaxe to obtain. The tree will drop a log, which you can use to craft 4 planks in your inventory. Then you can use the planks to fill your inventory's crafting grid and make a crafting table. You can place blocks by holding them in your hand and right clicking on the block you want to place another block on. 

The crafting table will allow you to create more complicated items, like tools and more "crafting stations." Most of these would take too much time to actually explain,  but the basic station you can create is a furnace, allowing you to smelt the raw metals obtained from iron and gold ore as well as a variety of other things by burning coal. While I have neglected to mention it so far, there is a button (added in more recent versions of minecraft) with a green book on it in your inventory that has all possible crafting recipes available to you. You have now experienced everything you need to play the game.

Other tools that you can craft or find will allow you to break certain types of blocks faster, with better tools lasting longer and being more effective. 

    The game itself mostly lacks a true "Tutorial" (Though the bedrock edition does walk through the basics whenever you create a world. No matter how many you've created, without an option to turn off said tutorial at time of writing). There are many aspects of the game that can be figured out on your own, such as certain ores needing a certain level of tool to be obtainable, with Iron and above being able to mine any ore and Diamond tools needed to obtain Obsidian and Netherite. 

    There is not, however, any in-game explanation of what a Nether portal is, how to light one, or how to locate Strongholds and The End. Marketing outside the game may depict the Nether or End portals, but how to use them is often not discoverable unless someone outside the game tells a new player how to perform those steps, despite recent additions by Mojang to make these features more accessable, such as the Ruined Portal structure and the visible path in the Advancements (Effectively achievements).

That being said, a nether portal created by using a minimum of 10 obsidian blocks to create a rectangular portal frame placed so that it creates a hole at minimum of 2 blocks wide and 3 blocks tall. This should look like a tall door frame, for clarity. Then you need to one of the bottom 2 blocks of obsidian on fire. TO DO THIS! You need to craft a flint and steel which requires an Iron Ingot and Flint. Iron can be found in caves and flint can be found by repeatedly breaking gravel. Put one of each in a crafting grid and boom. You can start fires now. Light the portal, which should now be filled with swirly purple textures, and stand in the purple. You will then be transported to the nether which is constantly on fire. To get out walk back into the portal after leaving the space it occupies.

 2-Slay the Spire https://store.steampowered.com/app/646570/Slay_the_Spire/ 

    A Card game based Roguelike with four different characters to unlock and choose from. -I've really been enjoying this game recently. Each run starts very similarly (with a few options to add variety) and relies on drafting a deck of cards by defeating enemies, making choices in events, and modifing the deck at shops and campfires. On higher difficulties some things are more up to chance, but that only adds to the choices that can be made when crafting a deck to help get past a certain boss or encounter. The very start of the game was just as fun, and unlocking everything was fairly quick, though I am still working through the Ascensions on several characters (The Difficulty modifier in STS).

 3- Yume Nikki https://store.steampowered.com/app/650700/Yume_Nikki/ 

    Yume Nikki is a top-down 2d game made in RPG Maker 2003, and was released in 2004. It was later re-released on Steam in 2008. The gameplay consists of wandering through a variety of areas attempting to locate "Effects" that you can use as costumes or powerups. While the goal of the game is to collect all 24 effects and get through a final area, the main appeal of the game is wandering through the different dream environments and encountering the rare random event. Discovering something new is almost always rewarding, since there are minimal guidelines. -Please note that many rooms contain flashing images, and are likely to be stumbled upon without warning.
