If you answered “yes” to any of those questions, I have quite the treat for you. The crew at the Internet Archive—go there now if you haven’t, just to see the awesome work they do—just put their collective foot into the “your downtime will never be the same” category with their latest endeavor. It’s the Internet Arcade, an aptly titled virtual smorgasbord of games from yesteryear that surely ate up all the coins you could find in your house, couch cushions, top of the refrigerator (my parent’s favorite change spot), etc…
After going decidedly old-school with their Console Living Room project—check it out, now—they have embraced some of gaming’s most crucial decades (namely the ’70s through ’90s) and uploaded 900 classic arcade games to their site. Yes, 900. Not 90—900. That’s… a lot of games, and they range from titles you have probably played to death (Destroyer, Ghouls N’ Ghosts, Golden Axe) to some you have likely never even heard of (Hoccer, Jungler, Kick Start).
Honestly, I don’t even know where you should begin, but maybe start with something you have never heard of or something you know by name but haven’t played. Then I recommend moving through the games you wasted so many quarters on, if only to be like “YEAH. YOU DON’T OWN ME ANYMORE, JOUST!” Or something.
You can play all the games at the Internet Arcade.
