Looking for game suggestions for ( online and offline gameplay ) for my Netbook.

I am going away on business trip for a week and thought of instead of bringing my massive laptop and running to airport terminals with it slung over my shoulder and CARRY on bag over opposite shoulder, maybe I should bring the Netbook with me instead and this way I have my backpack and a computer in 1 carry on item.

The netbook also has up to 9 hours of battery life on a full charge in case I get stuck in a long layover with no airport outlets to tap into or all taken by other electron tappers for their iPhones etc as has been the case in the past.

BUT... Given its a wimpy Atom Processor I haven't played any installed games on it yet to know what would even run on it. The only games played so far are Facebook games in which some behave and others seem to have graphics lag such as the simulated dials on slot machine etc:

HARDWARE:

Toshiba NB205-N210 Netbook
Intel Atom 1.66Ghz CPU ( 1 physical core but shows as 2 cores with virtual core )
Intel Integrated Graphics GPU
2GB DDR2 RAM
90GB OCZ SATA II SSD
Windows XP Home SP3 OS

Looking for any and all suggestions to TRY out on this netbook for both online and offine games. Free is good, although if they cost less than $20 maybe I will buy a title after checking it out online.

Thanks for suggestions ... I have some older games that would probably run ok on it, however most of them require the CD to be in CD ROM during game play as antipiracy feature and this netbook has no optical drive, however I have installed software to it via external DVD-RW drive connected to USB 2.0 before if need be to install a game that then runs stand alone.Unfortunately you have a weak graphics card so cant play high end games.
did you tried subway surfers ? there is windows version
warcraft 3 dota Thanks for game suggestions, going to check those out on it. I have Warcraft III, never tried subway surfers before will have to check into that.

As far as graphics processing power it is weak, its = to around a Geforce 4 MX 440 according to online benchmark resuts for GPU score.

I ended up taking both my netbook and my large laptop with me on the business trip because I didnt find a solution to pass the time on just the netbook. Going to try out Warcraft 3 on it to see how it performs. I have run Diablo II on it without any issues, but played that game so much that I lose interest with it anymore.

I also have TORCHLIGHT 1 and Torchlight 2 and those games are fun, but the netbook seems to lag with both of them and they require a live connection to Steam because even when setting them up to operate in offline mode through steam, but wont launch without an internet connection to Steam which I suppose is an antipiracy feature maybe, although other games not on this netbook but on my laptop seem to run ok in the steam offline mode for a period of time until the offline time lease is expired and has to be renewed through connection to steam.Tell me how the games worked especially Warcraft III. I think it would not be a problem to play it.
