"New/Old" Portal Maps - Why isn't Dice doing THIS >>

It doesn't sound fishy at all @DPsx7 ,

The overarching map idea and rough placement of congestion areas and content is of course there from the original map and game from the past.

But all the people who made all that work in the past are no longer around.  Neither are all their work considerations and learnings they made during all their many map design iterations and tweaks until they got the final version right.

Moreover the 'teleportation' of that old map design into a whole new game engine and game mechanics environment takes that all again needs detailed design works again from scratch to get it right.  Aka the coordinates from the old map can no longer be used in the new environment, every nugget on the map needs new placement and considerations, every building, what its made of and its destructibility, and every window and gate opening, etc.  Reasons are many, like soldier speed, weapon speed, damage ratio and impact radius, vehicle speed etc etc all are now having a new setting and setup of parameters in the new game platform, and that all changes the fundamentals if something works still in the new or not versus the old.

So do they save some time vs building something entirely new?  Yes.

But there is still a very substantial amount of design work, testing and reiterations involved to make it work on the new game platform vs the old.  Evidenced also when you play aka Caspian Border in the BF2042 Portal vs if you take the old version of the game/map for a spin.  The sensation is simply just not the same at all.  So why is that?

There is near an endless list of parameters that all plays a part in how the final game feels like when played by the gamer.  

Solid practical experience in doing such map design work is a special demanding science in itself.  And for what we have seen with BF2042, the EA DICE department is running short on these experts.
