The game fared quite a bit better on the DS, though-- graphics that were disappointing on the Wii looked much better on the DS, and the game contains the same drivers, missions, and structure. The stylus-based steering works much better in my opinion than waggle. I don't know how interested in historical racing games on the DS you are (I'm usually not very) but I enjoyed my five minutes with it, at least.
WordJong is the DS version of the online tile-based word game. You pull letters off the pile to form words; longer words net you bonuses. With no time limits, it's a nice, low-pressure word game. I have nothing bad to say about WordJong. In fact, I could see someone getting their $19.99 worth out of it.
Also on display was the Fullmetal Alchemist trading card game, which keeps the exact rules and card set of the trading card game-- which means that it was way too complicated for me to figure out in five minutes.
John Deere: Harvest in the Heartland is a farming sim that differs from Harvest Moon in both its strict focus on farming (versus Harvest Moon's relationships) and the ability to purchase John Deere farm equipment. There's enough going on here (planting, feeding, cleaning, building barns/coops/etc., all kinds of farmy stuff) that Harvest Moon faithful may actually give it a look. Not being a Harvest Moon or farming person, I just swept up some poop and giggled.
