Moon Patrol on the Atari 2600 (Emulated on my Steam Deck). I'm not giving away my age by posting this at all...

Played with various ROMs of popular late ‘70s and early ‘80s arcade games.

super smash bros melee (2001) but only bc the online they added in 2020 is so fucking good

Definitely some earlier Sega titles. Teddy Boy, My Hero, Wonderboy. Easy to grab at to entertain my toddler for half an hour so they get switched on fairly regularly.

R-Type, first release 1987

I just picked up "The Sumerian Game" on Steam. What a great story...

I played Beavis and Butthead in Virtual Stupidity, 1995 last time i streamed to nobody

I haven't exactly been keeping track but off the top of my head the oldest game I've probably played this year is A Link to the Past (SNES, 1991).

I got my childhood game, crysis 3 up and running with wine, so I've been plying that again. I can't belive it looks so good and runs so well compared to all the other "modern" games out there.

DMG Gameboy Kirby Dreamland. My youngest loves it and it's REALLY hard to lose so he doesn't need a ton of help.

I think streetfighter 2 But also just started a play through of Serious Sam TFE

Just installed an Atari2600 emulator
