This is off the top of the dome and given more time I'd probably change this significantly, but here's 10 of my favorites from a multitude of genres:

• Rain World
• Outer Wilds
• Stephen's Sausage Roll

(Those are pretty firmly my top 3, all totally mindblowing experiences that surprised and awed me multiple times)

• Spelunky 2
• Getting Over It
• Peaks Of Yore
• Satisfactory
• Dark Souls PTDE
• Hunt: Showdown
• Morrowind

Honorable mentions for Guilty Gear and Tekken as series, and I have a special place in my heart for the 2000 title Sacrifice, which is my eternal top pick for a remaster/remake.

In no real particular order, games with highest impact on me:

1. battlefield 1942 - desert combat mod

Ground breaking at the time. Physics and gamespeed have never been captured by any other game. Consumed my free time for a long time.

2 counter strike

Simple concept, extreme depth. I've clocked several thousand hours into this franchise.

3. The witcher 3

In terms of world building and story telling... Incredible.

4. The Witness

Absolute masterclass in game design, world design. Puzzle design.. This is an incredible puzzle game that will shift your perspective.

5. Faster than light

I haven't found anything else quite scratch that replay ability, that tethering on the brink of losing, itch. It's a unique game.

6. Guild wars 2

Completely changed the way mmorpgs were played, and was a great mmo.

7. Monkey Island

I wanted to mention a point and click, several spring to mind, but this still series lives in my mind the most. Although space quest is another that impacted my young brain.

8. Minecraft

Like... I was there since its debut. Still watching and enjoying mc related content.

9. Elite

Space is pretty big and cool

10. Eve online

Getting back stabbed by the person you've been back stabbing for, so you join the enemies of your friends to be able to backstab your backstabbers.

Football Manager phone versions.

All on Windows XP:
