IIRC the one I played ca. 2006 was called Globalia. It was super nerdy shit where you had to structure your posts like official government statements, very “model UN” kind of thing.
Shoutout to my based younger self getting to play Cuba and immediately allying with Al-Qaeda and trying to get nukes (they kicked me out for this)
Highly recommend creating a nation and just joining the Chapochat region if you want. It is a fun game to just play for thirty minute/day for a week or two here or there.
