Not games, but you’ve probably heard of the dozens or hundreds of interactive online museums. They got huge during covid proper. They have varying degrees of interactivity, but some are pretty good.

Here is a random site I found with a list.

I saw it mentioned in some YouTubers video about megastructure games. Looks interesting. Thanks

I don’t play with friends much but that would definitely keep people playing. I come back every once in a while when the game and mods I like update. It’s a big change if I wait too long.

Creeper world is cool strategy game that is like real time strategy and tower defense but the enemy is a liquid. You can place your guns anywhere and you manage your energy and infrastructure. Also there have been 5 or so games that are all related by the single dev since the days of flash games (5 mainline that add new features and sometimes switch it up and one related but unique game). It’s worth checking out knuckle cracker games.

Mine would also be Minecraft and probably the Creeper World series.

Both have been around for a while and are extremely relatable and have strong communities that keep them going and feeling new.
