It took me a second, before I realized you are not talking about two characters. I guess that's my cue, I've shipped too many pairs.
Ahh, sorry. Game dev jargon slipped in unnoticed. We use "shipping" games as the shorthand for what we give to the player.
It's used in software development and movies as well, but nowhere near as often as we do in games, allegedly.
The "Shipping" phase really is all about the final steps like finishing, polishing and releasing the game.
"Known shippable" is the term for bugs we're aware of, but feel like they can be in the game on day 0.
"Ship it!" is commonly heard when people are showing art, demo, etc. As a way to congratulate (Good work!) or simply say "that's more than good enough to go in the game as is"
