But I'd say.. So much for sticking to the established genre for Fallout. We all know what happened when they stepped outside the genre with BoS.
Funny thing, Bethesda themselves learned that lesson themselves, when they messed with the established genre for their "The Elder Scrolls" games.
Arena was a wordly FPS RPG. Sold nicely and set the standard.
Daggerfall was a wordly(huge) FPS RPG, and sold immensely, and really put the foundation of TES in concrete.
Battlespire was a non worldy FPS wannabe RPG, and did horribly, they had moved away from the TES genre.
Redguard, was a 3'rd person action game, wich sold so bad most TES players didn't hear about it, and moved them even further away from the TES genre.
See now? Bethesda themselves, learned that moving a game line away from its roots, was a BIG no no. Then they went back to their roots...
Morrowind came out as a wordly FPS RPG, and it became an instant classic bestseller.
Makes you wonder if they maybe hired some noobs that didn't learn the "genre roots" lesson that the veterans of Bethesda learned.
