I think the Pokemon DS games are some of the best you can get for the DS. I know lots about Pokemon because my eldest (10) has been into Pokemon since he was born and I had to help him on Pokemon Emerald when his reading was not so great. These games are so absorbing and the regions are immense and there is so much so catch and discover and find that even my youngest son who hardly played on his DS before is hooked. BUT the BEST thing about these two games is the POKEWALKER (which comes with the game and counts your steps when walking or running). Now you can balance a bit of game playing with good healthy exercise. When it's time to walk the dog we transfer a couple of Pokemon on to the Pokewalker and off we go, stopping a couple of times to catch our breath and see if we can catch a couple more Pokemon or find something useful. They hated walking the dog before and were dreadful for lagging behind on long walks but now they actually want to go. Also, you can still accumulate watts when riding a bike (we put ours in a rucksack pocket to keep them safe). It's great for getting your pokemon up a level. I'm waiting to see what a metapod turns into. Still got a lot to learn!
