Xbox One: 360 Backwards Compatibility, i'm now over 50 games

I like the concept of having backwards compatibility (i'd seriously consider a PS4 at the right price if they had PS One Classics - not PS Now, I hate subscription services).  However, I haven't really used it.  I don't know if i'm a fan of the new release non-schedule (i'd rather have 10+ games announced for the same day every month, like January 17th or something). 

The only game I have actually played on backwards compatibility (BC) is Kameo (Rare Replay).

So if I am not actively playing the games (52 + 5 games that were on Rare Replay and 2 retail game - the Fables), what am I using backwards compatibility for?  Basically, I am using backwards compatibility to free up disc space on my Xbox 360.  I have something like 300-400 GBs of games that won't fit on my hard drive.  I know I should probably buy an external USB hard drive for the slack, but am trying to put that off as long as possible.

I still have about 900 GB left on my Xbox One (including the base and a 2 TB external hard drive). 

Needless to say, my Xbox One game list is kind of a mess (I wish they would let you filter out BC titles).   

Video Games Vanquished in 2016 (Secondary Account)

This is the list of games I have beaten using my secondary gamertag (formerly known as the original Xbox 360 tag). 

Video Games Vanquished in 2016 (Primary Account)

2016 is here (unfortunately?).  The number at the end of the date has changed, not much else has.  Maybe this will be the year my backlog shrinks (not likely, though there aren't many games I want this year).  These are the games that I have beaten (usually that just means seeing the end credits for me) in 2016.  This is my primary account.

Most games will be on the easiest setting (because challenge = frustration and frustration does not equal fun). 

2016 Games i'm Interested In

2015 is done (finally).  So what games am i looking forward to in 2016, keeping in mind i'm not sure about "arcade" releases (and some unannounced retail games).  Have i done this before?  Probably, but i'm going to do it again.  i'm trying not to spend over $40 out of pocket for any game this year.  i am going to try and purchase Scalebound (if it releases in 2016) with Bing Credits (if i can save that many - doubtful).

This is US date format (month/day)

i Think i Might Need a Bigger Hard Drive

Recently, I have felt like I am running out of space on the hard drives for both my Xbox 360 and my Xbox One.

My Xbox 360
i am definitely out of space.  There are currently 4 games in my active downloads that wouldn't start due to insufficient space (under 100 MH).  There are also a bunch of games that are not currently on the hard drive.  There are at least 47 Games on Demand and 65 arcade games that are not currently installed.  Not including DLC, i'm short at least 330 GB for these games (i think i have a 320 GB drive on it, plus 4GB).

My Xbox One:
Maybe Backwards Compatibility can help me free up hard drive space on the 360.  That will just take up space on my Xbox One hard drive.  i thought that an external 2 GB hard drive would be enough for this whole generation.  i'm thinking that i might be wrong.  i currently have less than a TB of space left (and this generation probably has at least three years left).  i guess i still haven't installed Borderlands the Handsome Collection yet. 

Q4 2015 Games Acquired

I know I posted a partial (or at least incomplete) list of games in my backlog.  However, have you ever wondered what the last three months of the year purchases look like if someone went a little overboard (not completely overboard, just a little).  This also includes Xmas gifts.  Maybe this will help me with my previously unstated goal to get achievements in 40 different games in Q4 2015-2016.

Anyway...
