FWIW I tried SystemShock, first go rebooted my phone.
With a bit of overclock I got it to run... barely
The MIDI music chugged down to where I was always expecting a crash, I couldn't really understand most of the intro video.
It has been about 20 years so I dont remember all of the tricks but it is not really playable. Interestingly the emulator does not use up more than 50% to 75% CPU between 500 and 800mhz when I peeked at conky. If I can play SuperMario3D there must be a tweak to play system shock.
When everyone else was playing Doom the smart kids were playing System Shock.
