Dwarf Fortress?

I guess it's not really a text adventure, but still...

Dunno, but if you are a frequent online gamer you probably know that 'minimialism' is a frequently used tag over at Kongregate and that there many other minimalist games that are not text adventures.

Notable examples:

Momiga (http://www.kongregate.com/games/Rogerup/momiga) - one button, one dot

Midas (http://www.kongregate.com/games/wanderlands/midas)

This is not a minimalist game (http://stormalligator.com/this-is-not/)

Pretentious game (http://www.kongregate.com/games/keybol/pretentious-game)

Any of the later (or heck, even the earlier) Infocom text adventures are far from minimalistic. And contemporary interactive fiction written with Inform quite complex. Far more so than this.

Maybe something like roflbalt?
