and without him Fallout would be in an even worse position
To be honest that is hard to imagine as Troika and several other developer studios also showed interest in purchasing the Fallout franchise.
I never really understood the reasoning of trying to appeal a rather niche franchises to the masses.
Sure because of the money, but if people do it for that there are much more profitable franchises that appeal to the most common gamer who doesn't care much about non Hollywood style story driven stuff.
Bethesda would have been much better off creating their own Borderlands/Mad Max style Post Apocalyptic franchise which they can put in things like robots, vehicles, mutants, and so on.
I think this last decade has shown us how much the Hollywood style sequel/prequel/remake/reboot has failed from a production quality point of view.
Sure people talk about Star Wars and Star Trek again for example, but this is not the audience that is going to keep these franchises going on by purchasing the spin off products like toys, comics, duvet cover, commemorative plates and so on. (and that is how studios usually make more money as they get a percentage of all the sales on these)
Bethesda can only keep their Fallout games alive as long as they keep pumping them out and there are new gamers that want to play what Bethesda is offering them.
But the more Fallout games become like everything else the more gamers might start to wonder why they should play this open-sandbox-game with wacky characters instead of the other open-sandbox-game with wacky characters that are much more popular.
I am sure Bethesda will be able to put out a few more Fallout games but it is not a lasting video game name.
Open-sandbox-games are a trend right now as several have been announced (No Man's Sky), but trends come and go, we saw that with FPS and RTS games. There is still an audience for these but it is definitely not the size anymore that it once was.
