Your collection has a great mix of AAA blockbusters, indie gems, and sandbox games—but there are some **glaring gaps** in genres, gameplay styles, and must-play experiences. Here’s what’s missing and what to add:

---

### **🎮 Missing Genres & Must-Have Games**  
*(Sorted by Priority to Fill Gaps)*  

#### **1. Roguelike/Lite (Fast, Replayable, Challenging)**  
   - **Why?** Your library lacks "pick up and die" games perfect for short sessions.  
   - **Add:**  
     - *Hades* (PS4) – Best-in-class storytelling + combat.  
     - *Dead Cells* (PS4) – Tight Metroidvania/roguelike hybrid.  
     - *Returnal* (PS5) – If you upgrade, this is a *must*.  

#### **2. Metroidvania (Exploration + Progression)**  
   - **Why?** Only *Shovel Knight* scratches this itch lightly.  
   - **Add:**  
     - *Hollow Knight* (PS4) – Masterpiece of atmosphere and challenge.  
     - *Ori and the Blind Forest* (PS4) – Gorgeous, emotional platformer.  

#### **3. JRPGs (Story-Driven, Turn-Based/Tactical)**  
   - **Why?** Your RPGs are all Western (*Witcher 3, Fallout 4*).  
   - **Add:**  
     - *Persona 5 Royal* (PS4) – Stylish, deep, and addictive.  
     - *Final Fantasy VII Remake* (PS4) – Modern classic with action-RPG combat.  

#### **4. Survival/Crafting (Deeper Than Minecraft)**  
   - **Why?** *Minecraft* and *LEGO Worlds* are casual sandboxes.  
   - **Add:**  
     - *Subnautica* (PS4) – Underwater survival with horror elements.  
     - *The Forest* (PS4) – Horror + base-building (great co-op).  

#### **5. Puzzle/Logic Games (Brain-Burning Fun)**  
   - **Why?** Your library skews action-heavy.  
   - **Add:**  
     - *The Witness* (PS4) – Brilliant open-world puzzles.  
     - *Portal: The Companion Collection* (If it comes to PS4).  

#### **6. Horror (You Have Almost None!)**  
   - **Why?** Big gap for immersive scares.  
   - **Add:**  
     - *Resident Evil 2 Remake* (PS4) – Survival horror at its best.  
     - *Alien: Isolation* (PS4) – Unmatched tension.  

#### **7. Fighting Games (Beyond *Mortal Kombat*)**  
   - **Why?** *MK X* is fun but shallow long-term.  
   - **Add:**  
     - *Street Fighter 6* (PS4/5) – Best fighting game in years.  
     - *Dragon Ball FighterZ* (PS4) – Flashy, accessible anime fighter.  

#### **8. Immersive Sims (Player Choice-Driven)**  
   - **Why?** No *Deus Ex* or *Dishonored* here!  
   - **Add:**  
     - *Dishonored 2* (PS4) – Stealth + supernatural powers.  
     - *Prey* (PS4) – *BioShock* in space with deeper systems.  

#### **9. Co-Op Gems (Beyond *A Way Out*)**  
   - **Why?** More variety for multiplayer.  
   - **Add:**  
     - *It Takes Two* (PS4) – Best co-op game ever made.  
     - *Overcooked 2* (PS4) – Chaotic couch co-op.  

#### **10. Indie Darlings (Unique Experiences)**  
   - **Why?** You have *Journey* and *Flower*, but more gems exist.  
   - **Add:**  
     - *Celeste* (PS4) – Tough platformer + mental health themes.  
     - *Outer Wilds* (PS4) – Space exploration mystery (go in blind!).

### **💡 Budget-Friendly Picks (Under $20)**  
- *Hollow Knight*

### **🔍 Gaps Summary Table**  
| **Genre**          | **Your Current Gap** | **Top 1-2 Picks to Add**     |  
|--------------------|----------------------|------------------------------|  
| Roguelike         | ❌ None              | *Hades*, *Dead Cells*        |  
| Metroidvania     | ❌ None              | *Hollow Knight*, *Ori*       |

### **🎯 Final Advice:**  
- **Start with *Hades*** (it’s the best roguelike ever and fits short/long sessions).  
- **Then try *Hollow Knight*** (cheap, deep, and unforgettable).  
- **Fill horror/puzzle gaps next** (*RE2* or *The Witness*).
