having multiple people working on paradox is kinda hard since if there are lot they will all need a copy of rpg maker vx ace and then share the project like this p1 starts the project gives the date to p2 p3 p4 when p2 is done with what there are meant to do give the date to p1 to add to the main project to make sure nothing breaks then gives date to rest p3 and p4. that sounds like crazy amount of extra time and what if someone working got really injured, and if there not all together in the same building they have to find where they were working at just to get there data so and can add that to main project.
