I clicked because I was provoked by the unnecessarily large amount of exclamation points in the topic's title.
What do you mean by "What Would Look Better:"? What would be a better game, or what? In that case, I don't care which one, just not Mario Party DS.
SNES, NES, and other classic games are easier to find than you think believe you me, there are stores meant exactly for purchasing classic video games. They usually buy, sell, and trade video games as well as other mediums such as DVDs or CDs...just look around, they're everywhere
The PSP has homebrew stuff going for it which is neat and all
I find the DS to be a tad bit overrated, but I haven't played a PSP for more than two minutes so I don't know what to say, I can't have an opinion yet
My friend had a Game Boy Micro for a short while in 2005 when it was first hitting the stores. It was cool, the screen was really bright and easy to see for its size... although if I were to get an upgraded GBA, it would be the SP with the brighter screen which is a better buy probably
