Fallout: New Vegas looks awesome...
It's funny, I have many games that I haven't had time to play, but you bring them to our friends' house, with 5 kids there, and they play several of them in no time. However, they needed some help, so I helped them with Star Wars: Force Unleashed. Lightsaber dueling and force-throwing huge control consoles = FUN. Unfortunately, unlike with a Wii, only one person can play a DS at a time. So when everybody got their turn playing something, it was about dinner time. Later, we found a home version of "The Price I$ Right" on my laptop. (

I thought it only had arcade games). We managed to get to the finals and win the showcase. $38K... If only it were real...
We got home, and then left to visit my side of the family, and I brought the DS along to show my sister the bizarre button bar for Guitar Hero: Decades DS. (Her and her husband are big Guitar Hero/Rock Band fans.) For my hands, it works better to put just my left thumb through the hand strap, rather than the whole hand. The guitar pick stylus worked great. After a few tries at bass guitar on Paramore's CrushCrushCrush, I managed to get 37% before I crashed and burned. Not too bad...
Update: I also meant to bring an Atari 2600 emulator w/games on the laptop to the friends' house, but I didn't realize the games were in a separate install and ended up bringing an empty emu.

However, I loaded the games last night, and ended up playing a few (Robot Tank, Galaxian, MegaMania, Pole Position, Gyrus, Wizards of Wor, Adventure, BurgerTime, Star Voyager, GI Joe:Cobra Strike, Empire Strikes Back - what a nice trip back in time). So it should be ready to travel next time...
