1. so theres factions in this game but i hear theres 27 main quest is it like fallout 3 where you go talk to certain people to get the main quest then move on a linear pace or is the main quest able to branch out and complete it as one of the 3 factions/independent? also can you still complete the main quest if you were to say kill a main charecter or such like how in fallout you didnt need to do the quest up to a certain part you could litterally skip half the quest line

2. i keep hearing about these free quest what are they? are they like those unmarked quest in oblivion or kinda like when in FO 3 when you had to find those different audio recording things to get the MIRV but it didnt tell you about it in a quest log or such?

3. theres only one thing that could disappoint me with this game even keeps taking a dump on the graphics stating there horrible and such i have no problem with the graphics but all im wondering is how many textures/models from FO 3 did they reuse i hope i just dont walk into a town feeling like im walking into a town in FO 3 or walking inside a house with all the decorations, cabinets, stoves, etc looking the exact same as FO 3...

also i guess a 4th i heard companions can only die in hardcoe mode is this true?
