Eh, the only "seasons" I play special games for are Halloween (something spooky) and Christmas:
- Halloween - last year it was Darkside Detective and Return of the Obra Dinn - usually something spooky, but not into horror itself
- Christmas - last year it was Arida: Backland's Awakening and Opus Magnum; usually puzzles and heavier stories
This year, it'll probably be:
- Halloween - finally finish Metro 2033 series
- Christmas - probably some long game I've been sitting on, like The Witcher series or RDR II
Other than that, I don't really games based on the season, but based on time I have available and whatever interests me.
