>>55230195I only saw B2W2 additional content because it was one of the only 5 DS games I had (the other 4 being Mario Kart, New Super Mario Bros, Golden Sun: Dark Dawn and Worms).
I didn't had friends to play with outside, no money to buy more games (I had more than enough games according to my parents, which is understandable since I live in a 3rd world country and video games are a luxury for the lower classes) and also didn't have internet at home at the time (my parents tried various ISP but there were constant problems with the signal), so I spent most of the time trying to discover everything the game had to offer.
But even then I didn't discover everything and later learned about even more stuff because pokemon fans are autistic enough to almost always include extra content in guides/walkthroughs.
