I can cite way more than 5 excellent games from this decade from the top of my head, We’re almost in 2025, so I’ll limit to games released in or after 2015:

• Factorio
• RimWorld
• Stellaris
• Fallout 4
• Overcooked 2 (and all you can eat)
• Life is Strange
• Cyberpunk 2077
• Before your eyes
• Dead Cells
• Shadow Tactics
• Cities Skylines
• The outer worlds
• Two point hospital

I can keep going, but this is just from the top of my head, there are always good games getting released, and very rarely they’re AAA.
