What would be the time table for your Season Passes?
For me, I think any content that has mission rewards that can only be obtained once, and non-farmable bosses should not be packaged with the base game, even if it’s free, because if there are level cap increases, people will feel ripped off that they have to start a new character (or playthrough) to get that gear.
I would have the first Season Pass include the Takedowns, Circles of Slaughter, Trials, and Arm’s Race along with 12 Levels, bringing the cap to 62. An additional level would be unlocked every month, one Takedown every 6 months after release of the first. One Circle of Slaughter every 4 months after release of the first. One Trail every two months after release of the first, the Raid on a gap month, and Arm’s Race at launch, which would unlock once you beat the main story and unlock TVHM (included with base game, NVHM is level capped at 25 and scaled appropriately). TVHM will mainly be used to play these repeatable arenas and game types with them scaling to your level.
Sep - Arms Race + 1 level
Oct - Trial + 1 level
Nov - Circle of Slaughter + 1 level
Dec - Trial + 1 level
Jan - Maliwan Takedown +1 level
Feb - Trial + 1 level
Mar - Circle of Slaughter + 1 level
Apr - Trial + 1 level
May - Hemovorous Raid +1 level
June - Trial + 1 level
July - Circle of Slaughter + 1 level
Aug - Gaurdian Takedown + 1 level
The Second Season Pass would include Story content and seasonal events. Each Murder Mystery would be release individually like Head Hunter Packs, because that’s essentially what the maps are, but with a connecting narrative thread. In addition the fourth skill trees will be released to open the season pass and Mayhem Mode will unlock once level 72 is reached.
Sep - Skill trees + 1 level
Oct - Bloody Harvest + 1 level
Nov - Murder Mystery+ 1 level
Dec - Handsome Jackpot + 1 level
Jan - Murder Mystery +1 level
Feb - Guns, Love, and Tentacles & Broken Hearts Day + 1 level
Mar - Murder Mystery + 1 level
Apr - Revenge of the Cartels + 1 level
May - Murder Mystery +1 level
June - Bounty of Blood + 1 level
July - Mayhem Mode (includes Alternate Character Models)
Aug - Fantastic Fustercluck
Why save the Story content till year two??? Maximum time to make it as expansive and fulfilling as possible for narrative content and creative execution of level design and game play mechanics at end game.
