Fluxx

Fluxx and all the variants definitely meet all the requirements. However, if you want a strategy game its definitely not a good choice, so I expect this to get voted down just for that. Its a different game with two players, and fairly quiet if you ignore the zombie fluxx card that requires you to groan whenever a zombie creeper shows up. :)

Good travel games for two players, especially for playing on trains?
I have a new MacBook pro (I just switched from PC), and an older scanner (a Mustek A3 USB).

The scanner comes with drivers for OS 9 (I assume that's a non-starter on OS X), and Windows XP. 

I have Parallels Desktop 6 running a Windows 7 installation on my MacBook.

Windows 7 comes with "Windows XP mode", a Virtual Machine running XP. This is what I used to run my scanner previously, on my PC.  

However, Windows XP mode refuses to start inside the Parallels-powered Windows 7, complaining that the host machine (ie. Windows 7) doesn't have hardware-supported Virtualization. Whichis Parallels Desktop's "fault" as it's providing the virtual, simulated hardware.

Is there any way I can get Windows XP running on Windows 7 inside Parallels Desktop? Is there some setting I can change?

I guess simply creating a second Parallels VM running XP directly would be a workaround, but I don't have a separate copy of XP handy, and would like to avoid having to buy one.
