What's the oldest generation you still play regularly/semi-regularly?

[Spindel]

NES (so 3rd I guess?)

I still adore Metroid.

I love Kid Icarus, Simon’s Quest, LoZ 1 and 2, SMB 1-3, Blaster Master, Snake Rattle ‘n Roll, Guardian Legend and many more games.

Cobra Triangle is also a honorable mention.
