This is financially impossible for a small studio like Pipeworks. So rather than blow their budget on getting the rights to different versions of each monster, Pipeworks opted for fewer versions of a bunch of monsters.
Pipeworks wasn't picking up the tab, Atari was.
Toho puts the monsters into groups. Say if they want Godzilla, all Godzilla's are included except Burning Godzilla (although it looks like they got away with it by having the Critical Mass bit). All King Ghidorah's are included but Mecha King Ghidorah is separate. You get the idea.
