Just for anyone who cares, I played a bit more of the America Rising mod in Fallout 4, the quests are nice so far, voice acting ranges from good to laughably bad, there is a nigger character that has a ridiculously deep voice, Either the VA went over board trying to sound like a nigger or the voice samples were edited by the mod author, and there is a scientist lady whose voice lines have an echo. But others sound good at least by Fallout 4 standards.
Can't really comment on the Difficulty due to some mods I have, and I'm not sure exactly at what level the dev expected you to start the quest, since the first quest fires off as soon as you exit Vault 111, and fighting a Sentry bot at level 2 is a bit of a challenge, unless of course you cheese it.
So far I'd recomend it if you want to do an Enclave playthrough.
