Any discussion of classic Tomb Raider is incomplete without mentioning that the first Tomb Raider games are essentially exact copies of the original Prince of Persia game, translated to 3D. Not the level layout or story, but the control scheme – very distinct and not used by any other games – is identical. Also the standard traps are replicated, like collapsing tiles and spikes emerging from tiles.
Tomb Raider does add some flourishes, like the swan dive and hand standing ascent, and some necessary additions for 3D, like the ability to turn and jump sideways, but the rest is straight up Prince of Persia (the original 1989 one).
Whenever someone mentions Prince of Persia, I think about my first "hack" that was to edit the binary to add (I forgot what, immortality?).
This was one of the many pebbles that paved my way to IT and dev. Thank you.
