Need some nep on nep brawl

I really like the main line AND the spin offs. The spin offs make the series very creative and it gets fresh new winds. I mean its called HyperDIMENSION Neptunia. Of course they are many different games even the Neptunia RPG which is in 2D (DIMENSION!). Do you really want a series which is staying on the same ground like Super Mario Games?...

After playing it once or twice and then trying it a year later, the game refuses to get to the main menu and throws me this error: ___________________________________________ ############################################################################################ ERROR in action number 1 of Step Event0 for object game_initializer: Data structure with index does not exist. at gml_Script_load_game ############################################################################################ gml_Script_l...

Did I miss something? I don't have any problem with the game EXCEPT the game length...

Are we going to continue getting these obscure spin-offs and games\collabs\advertisements instead of proper sequels? It's been almost seven years since the last main Neptunia game...
