What order should I play my back catalog of games?

[twesterm]

So soon I will have a pretty large chunk of time to just game and after that I will be able to get into a normal gaming schedule again so that means I finally get to get to my back catalog of games!

Unfortunately, that means I have to decide which games I need to play.  I have about four years worth of games here that I need to play but don't exactly have four years to play them in.

So my question to yall is what order should I play these games?

• Paper Mario: the Thousand Year Door (GC)
  • It was like $15 new and heard it was awesome.  Still haven't even unwrapped it yet.
    
• A Vampyre Story (PC)
  • I've actually started and gotten a good way through this one.  I'm maybe four or five hours into it since I play it during lunch or dinner.
    
• Beyond Good and Evil (PC)
  • Only heard good things about it.  One of these days I'll get to it
• Limbo of the Lost (PC)
  • I just have to experience the horribleness.  I played it for about an hour, it was torture, but I still want to get farther.
• King's Bounty (PC)
  • Got it for free, might as well play it.
• The Witcher (PC)
  • Got it for free, might as well play it.
• God of War II (PS2)
  • I didn't like God of War but it was also $15 new so picked it up and never even unwrapped it.
• Dead Space (PS3)
  • Played an hour or so, loved it, and then never got back around to playing.
• Killzone 2 (PS3)
  • Played about 20 minutes, got two game stopping bugs, and just don't have the time to deal with that now.  I'll get to it again eventually.
• Resistance 2 (PS3)
  • Just haven't gotten around to it yet.
• Valkyira Chronicles (PS3) - picked it for $30 from the Gamestop sales
  
• de Blob (Wii)
  • Picked it up because I heard good things about it, haven't even unwrapped it yet.
• Madworld (Wii)
  • Played the tutorial and loved it, just haven't had the time to get further.
• Mercury Meltdown Revolution (Wii)
  • Saw it for $10, heard it was fun, haven't even opened it yet.
• Sam & Max: Season One (Wii)
  • Got it for Christmas, haven't even opened it yet.
• Alone in the Dark (360)
  • On loan from work, get an error about 90% of the time I try to start it
• Call of Duty 4 (360)
  • Got it really cheap, I'll get to it eventually
• Fallout 3 (360)
  • Started it and then got sucked into Fable II
• Lost Oddyssy (360)
  • Started it, got really pissed off at something, and put it down.  I'll start it again at some point.
• Saints Row 2 (360)
  • Started it, liked it, still haven't gotten around to it.
• Dreamfall: The Longest Journey (Xbox)
  • Got a few hours into it and really liked it, just ran out of time.
