Prince of Persia, 1989.

This game pioneered rotoscope animation and directly influenced the Tomb raider series in many ways:

• Crumbling slabs that you fall through
• spikes that kill you if you fall on them, but you can walk through them
• Clanging jaws that will chop you in half
• the re-cycling of multi-tier map design, when one big room with many levels becomes a central atrium to which you return many times, just sometimes higher or lower than you were before. Also a very clever use of limited memory resources.
• A random doppleganger encounter that hurts you when you hurt it.
• block-based jump physics with standing, running, and vertical jumping
• hanging from ledges as a mechanic
• little known fact about prince of Persia but if you holster your sword and hold X and T while drawing your sword, the player draws a pair of uzis instead
