I really enjoy singleplayer non-story driven games specifically roguelikes and some RTS/strategy style games. My top favourite games of all time are:

• Omori
• Stardew Valley
• FFXIV
• Danganronpa
• Age of Mythology
• Binding of Isaac
• Outer Wilds
• Sid meiers civilization 6
• Monster hunter: World
• League of Legends
• Rimworld
• Genshin Impact

(no particular order other than the top 3)
