I’m only still here because account deletion is broken on KBin.

Yeah but what expectation could they have had that they’d need to communicate with Bethesda in the first place? The game’s been “complete” for several years at this point, and IIRC Skyrim Special Edition (the Skyrim version of what happened here) was both announced in advance and released as a separate game, so mods that weren’t getting updates could still function. In light of that, it seems reasonable for the developer to expect advance warning at least in the form of a press release prior to the update being made available. Should they have reached out every week asking whether Bethesda had any plans to update a 10-year-old game?
I’d like to direct your attention to the prior games in the series we’re discussing, which have no such issues despite being made by Fromsoft. This “hurr durr issa Fromsoft boss get used to it” schtick is fucking insufferable and ignores the 15 years of history that company had before making those godawful Dark Souls games.
The arena is honestly pretty close to how it was in the old games. Hell, in 4A, if you beat White Glint in the story missions before beating her in the arena, you got to skip the arena fight entirely on account of her being dead.
Forcing players to use a specific build goes against the entire spirit of the series, though.
In 2 and (I think) 3, there was a fifth class of legs called “hover” that basically acted like quads do in hover mode in AC6, but bound to the ground unless you boosted. IIRC, they had the easiest time getting airborne from a boost, but had no unboosted jump. Basically, they were faster treads that could move sideways.
They’ve been gone since at least 4, though.
It’s a Dark Souls boss, not an Armored Core boss. AC bosses in previous games were usually (with the exception of For Answer) just other ACs with really good AI piloting them, not giant, unique things with mechanics that you don’t see anywhere else.
That alone is enough for me to wish they’d called it something else.
Because cars are a useful tool made up of physical parts that can wear out, while games are an entertainment product made of ever-changing software. You need a car. You don’t need video games.
