I could easily go either Minutemen or Railroad. The Minutemen basically seem to just want to help people, but are a bit too indifferent about Synths or ghouls. I wish they were replaced with The Followers of the Apocalypse for this game. The Railroad want to help people too, but can be a bit harsh towards those that don't agree with them. They seem a bit too indifferent about anything non Synth at times. The Brotherhood are zealous, xenophobic, and sort of hypocritical and almost cult like. They are too aggressive and seem to just want to control what they can get away with. The Institute is basically ok with nonhuman slavery. They don't understand what they are doing and seem in denial of what they have actually created. A Synth rebellion would eventually happen down the road, and rightfully so. No self aware life will be ok with being slaves regardless of what they are made of. Ultimately I sided with the Minutemen. Seems the most neutral and it's the least amount of bloodshed if done correctly. But I wish I could have just shut down the Institute instead of blowing it up and killing everyone.
