The one that comes first in my mind is none other than:
The Street Fighter II combo system.
In the original SFII arcade, combos chained from a regular attack move to a special move resulting in unblockable consecutive hits were in fact originally a bug/glitch in the game. Later everyone started exploiting the system, eventually becaming the norm as Capcom and other companies started making fighters based on the Combos System resulted from the glitch.
Are there any other games with glitches that became a standard as well?
