Handhelds are great! I still have my original Mattel baseball. It is crappy that I have to stock 9-volt batteries. But it is fun. The Coleco tabletops are great. I wore out my Coleco rechargeable battery pack. It had a 9-volt adaptor that plugged into C size batteries.
Now, I spend more time with the PSP. Pirates and EA Replay. EA Replay has some really good 16-bit classics, of those, Road Rash 3 and Desert Strike get the most game time. On the DS, my family likes any racing games. The ability to play against four people in one room, since we only have four DS systems. That is time well spent.
