Suggestions for games to take on a long flight.

I'm flying to Maui on Thursday morning from the west coast so I'm looking at 6+ hours trapped on a plane so I'm looking for a some distractions to kill time on the flight. I'll have a couple books and my netbook (1201N) but that'll only take me so far before I need to change it up.
I've got a DS, a PSP (1st Gen) and a the aforementioned netbook but the first two haven't been used in quite some time (DS = Scribblenauts, PSP = It's been in a box for years). What are some good, time consuming games that'll help me avoid wasting money on in flight entertainment?
Addendum : Previously on the DS I've rocked PuzzleQuest,  Disgaea  and Advance Wars to some positive effect but I've played my fill of each.
I'm also considering just watching Movies / TV on my netbook but I'm worried about killing the battery. It's rated for 4+ hours but 1080p can be murder. I haven't discounted loading Steam on it but:

• It's a netbook aka not a powerhouse.
• The touchpad and mouse keys suck balls.
• No guarantee that I'll have access to an AC outlet.

You consider 6+ hours a long flight?
 
And definantly Pokemon, I can waste days on those games.

Try to get Typing of the Dead on your netbook. Guaranteed fun.

I've had to go on my share of long-haul flights, and I've found that I rarely actually want to sit and think to play video games. I say you just download Arcade Fire's Funeral, bring a nice pillow, listen, and sleep.

Final Fantasy Tactics, Monster Hunter Freedom Unite, God of War, Syphon Filter, Metal Gear Solid, Jeanne D'Arc  for the PSP 
 
What genres do you like? 
 
I'm guessing you must like JRPGs, puzzle games or shovelware seeing as those are the only genre of games the DS has. 

Please be joking about the 6 hours being a long flight. I find sleeping, reading and movies to be the best things to do on a flight, gaming takes too much concentration. Tho the Phoenix Wright games are excellent if your interested. 

Patapon 2(PSP) 
Phoenix Wright: Any of them(DS) 
Pokemon games (DS) =D 
 
And for your.. brr, Netbook, something it might run? 
Mahjong or Solitair

• I was considering Phoenix Wright and the like or Professor Layton but was on the fence for some reason (not engaging enough?)
• I actually actively dislike JRPG (I blame FFX) but have a soft spot for tactics / turn-based games on mobile platforms. I think I've logged a 100+ hours on the FF:Tactics Advanced. I might have the second one as well but FF:Tactics Advanced came during the hay day of public transit on Seattle.
• GoW was on my radar but something about the PSP's "thumb stick" murders my fingers. I would actually consider getting a Go! if it's been fixed at this point but, like I said, I can't remember the last time I picked it up. I'm thinking it was when Crisis Core came out.
  

regardless of what system you own, there is only one correct answer.
 
Pokémon.

Phoenix Wright would be an excellent game to take, you might even finish it as well.

If you do decide to try something on your netbook, I suggest Torchlight.  It runs on a lot of low hardware specs, but you should check and see just the same.  For the DS, even though you dislike JRPGs you might want to take a look at The World Ends With You.  It's fun and different than your standard JRPG. 

My 20 hour flight to Europe next month must be fucking EPIC if 6 hours is long...

pokemon, layton, elite beat agents and the pheonix wright series helps me thru long flights.
Also, if your on a 10 hour+ flight, get drunk... My trips back and forth to Japan takes around 11 hours, so i usually spend the first 3 hours getting drunk, then i can sleep for 5 hours and then its only 3 hours left...

Pokemon, just like everyone else said.  Other games could work too but c'mon, its pokemon.  

@Captain_Insano

Pffft, both of you guys are wimps! My flight to Mars tomorrow is going to be 76,403 hours long!    

I wasn't expecting such a Pokemon contingent on this which is surprising. Not that I have anything against the series or the people who play them mind you just didn't seem that GB was 'that sort of place'.
I'm thinking it's going to be Layton & Wright at this point. They were already on my list but polling random strangers always seems to work.
However this is all moot if my step-daughter commadeers my DS to play (uughhh) Scribblenauts. I suppose I could use it as a reason to get a DSi and get in on some of that HOT DSi downloadable clock action that I've heard so much about.

Well the update to this situation is that, lo and behold, I can't find my DS lite. Last time I saw it was with my step daughter but it seems to have vanished from the apartment. Now I'm tasked with either buying a new (or DSi / XL) or just making due with non-handheld entertainment. PSP sort of fell to the wayside when I saw the suggestions come in and knowing my luck, it's disapeared as well (not having good luck with handhelds).
6+ hours of Bejewelled 2 on my iPhone it is!

Get free peggle and a decent playlist of songs. The 6 hours will fly by

Shiren the Wanderer! It's a great game with tons of replay.

Peggle or any Pop Cap games. ZUMA!!

Phoenix Wright!

I've almost destroyed peggle. Just a couple more levels where I haven't gotten 100% on. I fear for my families safety and the safety of those on the plane if I try to finish them. I'll either go ballistic after the failures or go super saiyan when I finally manage to do it.
I guess I'll make a decision when I go to pickup my GoW3 pre-order today. I've got purchase some filters for one of my lens and their price will determine what my CRAZY CA$H situation is like.

Epilogue
Camera filter won out. 82mm filter aren't cheap apparently and I had to take a hit.
I just remembered that I'd already bought 'The Dig' and the old school Indiana Jones games on STEAM so I'll be playing that on my flight.
