1. Rogue Legacy

I could play it endlessly. Death is expected and you constantly upgrade. And when you have a good run it really feels like you've earned it, as opposed to a lot of Rogues that make you feel like you got lucky with buffs.

2. Final Fantasy VIII

There's so many ways you can play it. And there are so many ways to grind beyond the typical RPG way of killing more monsters.

3. Morrowind

It's simply the most amazing world to get lost in. There's something to do or explore around every corner. And the game practically begs you to break it.

4. Final Fantasy XII

This one is my current game. They made an ATB turn based system somehow real time. And it's so cathartic to wonder around beautiful landscapes killing monsters in classic ATB style seamlessly.

Assassin's Creed 3. I know I'm probably the only one in the world but I love just getting lost parkouring through the forest and hunting animals

Borderlands 1

It's the perfect game. The story is tight. The builds and weapons are fun. It's not too grindy, but you can benefit from grinding if you want to. The post-apocalyptic trash planet setting has yet to be diluted and the characters have yet to be flanderized by later entries in the series.

It's a game that I can pick up anytime and just vibe. My favorite part is collecting all of Tannis' ECHO Logs throughout the game and getting to follow along with her trauma and descent into madness.

It helps that it has the second best DLC in the series to date. Secret Armoury of General Knox is chef's kiss. Assault on Dragon Keep is only better by a hair.

Don't Starve Together. I suck at it, but I love opening up the map and building up my base.

I have over 500 hours in Particle Fleet: Emergence. Very chill level-based game where you can slowly move forward and beat a map over an hour or so. All the Knuckle Cracker games have tons and tons of user content available so there's no shortage of maps to play.

Halo 3, any of the older guitar hero or rock band games. Or OSRS.

Killing Floor. I'll probably be playing that game till the day I die.

Dragon Quest!
