There are games that are entirely text-based. I play less than I used to but always try to check out the yearly winners on https://ifcomp.org/

There are a lot of MUD games. I've been playing WoTMUD on and off for a little over two decades now.

Pretty sure those still fit the thesis in practical terms. They demand more of the player, and AFAIK are not particularly associated with childishness (if only because much fewer people know they exist, but still, you can't take imagine people thinking some arty piece of IF is childish, can you?).
