I need advice - The capstone to a year-long gaming challenge

I need some advice/a recommendation.

I have been in a gaming rut over the last little while and I started a challenge at the start of 2021 to get me out of it. I felt like I had just been playing the same games over and over for years and my passion for a hobby I've been doing since forever was dying out.

The challenge was simple: complete 21 games in 2021.

Now that doesn't seem like a lot, but I was in a rut so it sounded fun enough. It's taken me on one of the greatest gaming adventures I've had. I've played RDR2, Ori and the blind forest, a full run of Rimworld and many more. I've tried my best to play as many different types of games as possible.

The thing is that I've finished the 20th game (Outer wilds) and I'm ready for a capstone. A big finish. I want your help in choosing what that is. I've narrowed it down to these:

​

• Halo 1-4 and ODST (I'm counting the Master Chief collection as one)
• Hollow Knight
• Frostpunk
• Death Stranding
• Factorio
• Divinity Original Sin 2
• Undertale
• Control

Note: I'll be going in blind to all of these games.
