Similarites between "The Terminator" and "Aliens"

These are some similarities I noticed between The Terminator and Aliens:

1) Both were directed and written by James Cameron, with Michael Biehn, Lance Henriksen, and Bill Paxton, produced by Gale Anne Hurd, with creatures by Stan Winston.  If an actor dies in one movie, he doesn't die in the other: Paxton's death is not confirmed in The Terminator, as he's merely shoved aside, so he's counted as living.

2) Similar company names: Cyberdyne from The Terminator, Hyperdyne from Aliens.

3) There's a mention of a "phased plasma rifle."

4) Michael Biehn's right hand is bitten by a human.

5) Michael Biehn's character has a similar pump shotgun in both movies.

6) Michael Biehn is wounded near the end, and a woman helps him along.

7) The title villain is vanquished by the heroine using machinery: Sarah with the hydraulic press, Ripley with the load lifter and docking bay.

8) The climaxes have similar looks, with claustrophobic locations, blue, white and red colors, lots of metal, and smoke.

9) Lance Henriksen is a robot in Aliens; he originally was going to play the Terminator.  If that had happened, then his character in both movies would have ended up as a torso.

10) A robot ends up as a torso that keeps moving.
