You can make a game about anything that is dead or has died on the Internet (e.g., Internet Explorer).
This isn't a strict jam or competition. So you can play around with how you interpret the theme if you like.
There's a list of ideas on the main page too:
‣ Dead or defunct software, degradation, lost memories, ambient archiving, webcore or vaporwave art and digital history.
‣ The march of time and how it changes familiar things.
‣ Internet memes, conspiracies, cursed chain letters and early forum communities from the 90s until early 2000s.
‣ Keeping to or emulating the limitations and innovations of games from before the late-2000s.
‣ The era of Internet Tool Bars and instant messengers (AIM, ICQ, Usenet, MSN).
‣ Popular websites or communities you used to visit (Netscape, GeoCities, NewGrounds, early Youtube, Machinima).
‣ Nostalgic technology and gadgets (Dial up modems, HTML code easter egg hunts, demo discs, CRT monitors, Torrents).
‣ The birth of the Internet (January 21, 1983) or your first encounter with it.
‣ Experiments and art from your online childhood (MsPaint, netzines, WordArt, blogs, disorganized fonts on an animated space background).
‣ Friends or things you made online but forgot about.
‣ If you never saw the early Internet, what do you think it was like?
