SUUUUUUURE it was your girlfriend...
I "borrowed" a copy of squad command when I was having a look at a DS emulator and it was pretty good (though incredibly slow, my lappy was struggling with the emulation). Very much like the old Chaos Gate game only slightly faster to play. I was rather tempted to get a DS and the game and got to the stage of watching a few on ebay when I sort of realised that there was nothing else at all on the DS I was interested in and when I added the cost of the game and console together, I'd be spending more than au$200 to play ONE game.
If you've got a DS or PSP then I'd say yes, it's worth getting.
