Too many games, too less space (and time)

Here's another meaningless blog by me :D
So my holidays are going on, and I've been trying to catch up on a lot of games I missed out in the past few months. 

I just got Battlefield Bad : Company 2, and as a newborn in online FPS multiplayers, I'm kind of having a tough time :P  I also got Split/Second (which is a great game) so that me and my friends could have some exciting racing action on splitscreen.  Now I need to keep these two on my 160 GB HDD, as I just got them and am enjoying them. 
 
Now, alongside this, I also have the MoH beta. Now I don't really need to keep this one as I'm already playing BF:BC2, so playing a beta of a similar game doesn't make much sense. Also, I have played quite a lot of it, and have had my fill. Since I don't really plan on getting this game right when it comes out and dive into the MP, I don't need to level up my character with the beta till then. But you don't get beta keys everyday. So I'm finding it difficult to get rid of this 
 
Also, I have about 5 GB of Runes of Magic on my drive, which I'm playing with the Giantbomb dudes. We just got our guild castle and I really don't wanna leave this, as it's a blast playing this game with the GBers. 

Alright, I still have about 20 GB free spread over 4 partitions, but I'm not really satisfied with the games that I've been playing as I'm an RPG fan, who needs good single player stories to be entertained. For that, I got DA:O Awakening.  Having LOVED Origins, I'm pretty sure I'll enjoy this one too. But the trouble is, it needs DA:O to be installed to play. Which will take about 15 Gb more. And then I don't know how many GBs Awakening itself will take.
 
So yeah, I'm out of space and my holidays are running out (not really, but you know). I really wanna play Awakening and BFBC2 and I need S/S as my friends will be coming over to play everyday and it's a great splitscreen game. Things are really getting awesome in RoM, so I don't wanna get rid of that. The MoH beta is only 700 MB so there's no use of removing it. 
So yeah, kind of in a weird fix. Need to find some way out of this. How about you guys? How's your holiday gaming going? 
 
PS : Don't take any of the above seriously. I just found out I have 7GB of worthless old backup on my HDD waiting to be deleted! Sorry for wasting your time XD
