I wanna start a thread about game mechanics that totally glitch and mess you up. The kinds of games where you couldn't just execute an action, but you also had to anticipate a malfunction. Some examples I'm thinking of:
Metal Gear Solid- When choking a guard, sometimes I'd get too close to him and it would activate the Alert phase...even though I had the guard subdued and he didn't see me.
Tenchu Series- Alerting a ninja foe and while running away, the same ninja foe would re-spot you, again and again, triggering the alert phase many times, even though he still only saw you the same one time.
What experiences have y'all had?
