I am only on level 25 .... having done a restart on my first attempt as i couldn't get the hang of base building . Which i think as a very good feature , when you get bored you just spend time building I was reading the OP's original post and was about to disagree , but then after the initial paragraph - I tend to agree with him on everything because of my fear of the main story ending prematurely ( like VEGAS did ,producing a anti-climax ) I am doing all the side quests and am at a stage, now were the MINUTEMEN quests are just repeating themselves in the same locations . Part of me likes it , as it gives the game longevity but it is very boring to clear out the same area's all the time , time after time . I would whole heartily agree - i miss the caves and underground systems and i would love to see notes ,holotapes with mini quests and rescues more frequent in the game for me - fallout 3 was the best ...Vegas was ok but it just was not as expansive as fallout 3 ... i liked the different ammo feature AND as for fallout 4 , i do like it but i wandering around thinking it's going to end ... the attacks on the bases need to be more frequent also
