The reach of UUe's arcade is determined by the extent of its orchestra, particularly the ballet's (Mathilda) lyric installation. (see Egglepple, Everywhere!) Among other things, an arcade may feature UUelcome presented in gamemode.
Note (+): In position and momentum space, arcades may be of arbitrary size (i.e., (n+1)-dimensional), and are smart by default. They themselves may be virtual, physical, or hybrid. Our preference is the simulated environment.
