AD is a testament to the skill and passion of the quake mapping community (❤️) but it's also a monument to excess.
2+ hours , 250+ enemies, and 25+ secrets per level is just too much. no map concept can survive that kind of overexposure.
for my money (lol) something like the snack pack or the 100 brush maps are better examples of quake level design: short and sweet and not as concerned with spectacle or polish.
AD is super worth playing, if for no other reason than because it's an important cultural object, but i do not enjoy it.
