This was such a weird game. I owned it and I think I completed it (in that I... guess I watched all the TV... fml) but I am soooo glad I never paid for it.
The novelty of the game, for me, was entirely in the fact that apparently Nintendo gave a copy to my friend who ran a fairly popular Pokémon website at the time and she was permitted to do a giveaway for it. I entered, presumably along with a lot of other people, and won. To this day I still don't know if she rigged it for me because we were friends (although at the time we hadn't really talked in a while so...!) or if I won fair and square but hey, no complaints here. Except maybe for the fact that I felt obliged to finish the game after that--*shot*
Actually, I'm being too harsh. I did actually enjoy the game if only because it so heavily featured the Pichu Bros who were my favourites at the time. (This was looong before Cherrim existed, after all.) I didn't mind rewatching that same stupid segment over and over and over because it featured my favourite Pokémon characters. :>
