Here is Bentley Bear creator Franz Lanzinger talking about the making of Crystal Castles at the Game Developer’s Conference. Skip to 27:50 to see Franz give a live piano performance of the game’s soundtrack.
What do you do if you have an arcade game that doesn’t have a bear in it? Follow Bentley’s advice: deface it and turn it into the bear game it was born to be! Take that, Dig Dug.
Bentley Bear Trivia: In prototype versions of the original Crystal Castles, Bentley Bear’s name was Braveheart Bear 
This is Bentley Bear, star of Atari’s 1983 arcade game Crystal Castles. Bentley is the bear that we get the most requests for, so instead of just one post, today is the first annual Bentley Bear Day. A series of pictures will follow.
In the early days we painted target on video game bears and shot them, which is insensitive and wrong. But these games were products of their time, and to ignore them and pretend they never existed would be a bigger crime than the one they committed in the first place.
This is Sega’s 1980 arcade game Carnival, which asked players to repeatedly shoot this poor specimen between levels. I definitely do NOT approve of this, but it’s important to learn from the mistakes of our past.
This cute little white fellow is a pioneer among video game bears because he was one of the first ones.
The reason the player has zero points here is because he hasn’t befriended the bear yet, after he does all the zeroes are replaced by 9s and a happy song plays (and then the game crashes).
When a bear is driving it is important to always have a full honey pot. This ensures the safety of pedestrians but, more importantly, the happiness of the bear.
Warning: do NOT buy this game. Despite the artwork on the cover there isn’t actually a bear in it. I played it for weeks. I don’t know if my copy is broken but just in case, DO NOT SUPPORT THIS GAME.
Smokey Bear for the Atari 2600 is notable because it never actually came out. Actually none of these games did.
Many historians believe that had the game been completed, Smokey Bear could have prevented the video game market crash of 1983 in much the same way that he prevents forest fires.
