Alright, this is kind of a random story. 
 
I was going through my memory settings in my 360 deleting things (mostly because I'm mildly OCD, I have more than enough storage space).  My "Borderlands" section caught my attention, sitting at almost 2 gb's worth of data.  "I deleted my installed version after I was done with the rental," I said to myself.  Curious, I clicked open the folder.
 
Apparently, on March 1, 2010, at 2:36am I bought, downloaded, installed the Secret Armory of General Knoxx.  
 
Now, I don't even OWN Borderlands.  Hell, the only time I played it was when I rented it for an all nighter a friend and I had when he had leave from the Marine's.  After that, I returned it and never thought about it again.  It burnt me out a little bit, getting to level 23 in one sitting.  On top of that, I don't play video games that late on school night's.
 
So now I have a dilemma.  I didn't even notice the 800 points missing, only the fact that my Borderlands folder was taking up more space than what 2 save files should have.  Obviously, I can't get a refund for this.  I'm assuming it was one of those "someone was messing with a controller when the DLC was on the front page and hit A 3 times" which resulted in the purchase.   
 
I don't really want the purchase to go to waste, though... So my only option seems to be buying it.  Considering I still have a sour taste in my mouth from playing it for so long in one sitting, I'm asking you guys: has it held up since launch?  Is it still fun for you?  
 
I guess I just wanted to share my story.
 
 
 
 
EDIT: I figured it out.  The mystery purchase.  My parents were gone that week and Sunday night my brother thought it would be a good idea to throw a party.  It went on until well after 2:30 am, and they were using my 360 to play music.  Some drunk bastard must have bought it accidentally.

I got a little burned out on it after playing it for a few weeks and leveling to 31. I still really enjoy the game, I just played too much at once. I would say you might like it more if you came back to it. 

Yes, but only if you have people to play it with, online or otherwise. It's been on the front page of GB for a while, which is usually a good sign when it comes to a game's longevity.

Also, there should really be a mandatory password required to purchase shit.

I leveled to 50 and I would get the dlc if I had any points.

This story became a lot less fun once the mystery was solved...

I actually just started to enjoy it a lot more too. Ironically, it was when I started to play solo. With 4 players, the enemies seem to soak up way too many bullets.
 
Not to mention, the game certainly looked and ran much better when I upgraded my computer.
