I found a neat Wikipedia page with a lot of old C64 box art, so I figured I'd post my favorites over here. I tried to find a variety of different styles. Sorry for the low resolution, I'm not sure where to find better versions.
If there's interest I'll post more, and from other systems.
Bird Mother has a very nice cover! That also underlines the great theme of the game. I think the game is absolutely fantastic. Completely without space, platforming, or any of the other stuff that seems to be in every other game. A mother bird building a nest for her chicks and feeding them. I often let my 8-year-old daughter play this. Thank you for the pics.
I never had Bird Mother, but I looked up a playthrough and it's very charming!
I found a rom and gave it a go. It's a fun little game.
