Almost everything is boxed up in the storage room to keep it safe. I own large collections of Sega Saturn, PS1, PS2, Game Cube, DS, Mega Drive, Master System, SNES, N64 & Wii U games. I used to have a large Dreamcast collection but I sold it.
I own Smaller collections of GBA (used to have a lot more before I sold them), 3DS, Wii, PS3, PS4, X360, Game Boy, Game Gear, NES, Win XP PC, & Switch (Physical copies).
As for digital games... too many. I don't keep track of my digital purchases across all the platforms I own that have them. Xbox 360, PS3, PS4, Wii, 3DS, Wii U, Switch, Steam, GOG, Epic.
Steam says I own almost a thousand games on that service alone & I believe them.
