Honestly I was happy for the “interruption” in BL3, if you can really call it that with all the references in game plus the DLC that is still basically jacktastic. I feel like GBX started relying overly on the character after the big burst of popularity from BL2. After Jack died he got a pre-sequel documenting his early life, a telltale game in which he plays a major role, at least 3 DLC titles that focus on him, his actions, or situations he engineered, and a character class that was mostly just “Play Jack, but a weenie.”
It’s not that I dislike the character, but there for a while it really felt like whenever GBX had a weak quarter or needed to add some “spice” to any portion of the BL ladder, the answer was “eh, somebody write something for Damien and throw Jack in.”
Before I truly “miss” him, I’d need to see a full game that doesn’t try to throw back to him in some way. I love the character, but I’m a little jacked off at this point.
