Training games have been big on the DS, and a few have made it big on the Wii -- most notably, of course, Wii Fit -- but the lion's share of these "games" have remained on the DS. Big Brain Academy and My Word Coach are a few that have been on both systems. Have you tried them on both? We'd love to hear opinions about training games crossing the gulf, as it were. We're of the opinion that they're better when they're designed specifically for one system, and can thus play to that system's strength, but there are always exceptions.
