My only significant gripe was the fact that the Songbird was under-used. I think we should have fought him at regular intervals, there just needed to be more a sense of relentless pursuit.
I completely agree with this, the entire time I was playing I was waiting for Booker to blast him with a fireball or lightning or -something- when he came after us, always frustrated when he just cowered and let it have its way.
I was also disappointed at the distinct lack of handymen battles. I only fought 4, iirc, and they were the only enemies that gave me any kind of trouble throughout the game. Should've been more.
Since achievements accumulate, I wish there was a menu where I could track their progress (similar to the way Mass Effect 3 does it). Also a menu that lists all of the voxophone recordings and sightseer spots that's been collected. It'd make it all much easier to track.
So anyone that got the songbird edition got a code for a free soundtrack but it was not a complete soundtrack! Sure it had all the in game music but it didn't have all the old school songs you would hear on the radio there was at least 8 more songs from the radio they could have thrown on there also we should of got the seasons pass for free since the songbird edition was $160 but oh well pretty decent set other than that.
Minor huh? well let's see I got quite a few ,BUT I'll list the main one.
Weapon Upgrade Detail. By that I mean when you purchase an upgrade you saw a visual upgrade for it. Like in Bioshock when you upgraded the shotgun you saw gears housed in it and the pistol had that Extended magazine sticking out. That sorta of detail.
