Help with deciding what episodes to sample from TOS

[Admiral Archer]

Hey everyone! So I have recently discovered that Amazon offers digital episodes of Star Trek TOS, the way I prefer to view them: with the unremastered, original visual effects. I immediately purchased The Trouble With Tribbles, but I want to do a sampler with three more episodes to get a better variety. My question is this: of the list of episodes I have provided below, help me pick the three best or most iconic episodes from across all three seasons. Thanks!

-The Cage
-Where No Man Has Gone Before
-Balance of Terror
-Arena
-The City On The Edge Of Forever
-The Enterprise Incident
-All Our Yesterdays

 

[Warp Core Breach]

Where No Man Has Gone Before.

Balance of Terror.

The City on the Edge of Forever.

If you need a fourth, maybe substitute The Menagerie for The Cage, since it's basically the same thing with a framing story.

 

[The Salt Umpire]

Where No Man Has Gone Before.

Balance of Terror.

The City on the Edge of Forever.

I would add either Amok Time or Mirror, Mirror.

I would also expand your list to include "The Corbomite Maneuver." As the first production episode to be filmed, it established a lot of things the pilots didn't.

You have very little second season, what about adding "The Doomsday Machine?" I know this is more than you want but still, the early part of the second season had some of the best episodes with Gene Coon really settling in and getting the character interaction better than any other time during the series.

If you are sticking strictly to your list, these are the ones:
Balance of Terror
City on the Edge of Forever
All Our Yesterdays (a very underrated episode because it is in the third season but it is one of the best)

 

[1001001]

Balance of Terror, for sure.

That’s my favorite TOS episode.
