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

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

Just installed an Atari2600 emulator

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

This year? Probably whatever the oldest game in the Switch's NES library? I haven't played much this year. Of note is Star Fox. I specifically played the first one. Star Fox 2 is interesting. It never got released but is on the Switch NES player. It has some rogue like features you'd see in games today. It has an xcom vibe where there's like an overworld map layer.

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

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.

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).

Robotron on mame and yar's revenge on 2600.

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

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