Honestly, I think the problem with Black/White was that there was very little lasting appeal compared to past games. I mean, people SWEAR the lasting appeal compares to D/P, but I don't think it even compared to R/B. I mean, B/W had really cool Pokemon, amazing graphics, and a deeper story. But there was nothing to look forward to. Just more of the same the entire game. They spent too much time on battling and exploring, and not enough on other things. They have one diversion outside of battling, and it's complete fail. Unless you count all the stuff you can do ONLY if you have online on your DS, which not everyone has. Honestly, I think it was the things to do outside of Battling that made Platinum/HG/SS/Emerald so fun. Like if you wanted to take a break from battling, you could do all sorts of things. And I thought digging up fossils, playing the super contests, making poffins, attending the Pokeathelon, making secret bases, as well as other things was fun. Black/White didn't have any of that, and the sad thing is that Black2/White2 isn't going to have much either, despite people saying the second games generally have a lot more stuff. Again, Black2/White2 seems too focused on battling and exploring, and not focused enough on the lasting appeal. I mean, the Pokemon World Tournament sounds fun, I guess, but I'm more interested in the mono-type challenges more than anything else. Pokewood/Pokestar doesn't sound much better than Pokemon Musical, which... I cannot believe Game Freak thought the Pokemon Musical was a good idea. Collecting Medals is basically the only thing to do besides battling, and I'm not sure that is even going to count. (Pokewood/Pokestar is still mostly battling.) I mean, yes I get it, Battling is the point of the game. But like I said, it was the things you could do outside of battling that gave Pokemon its lasting appeal.
Honestly, at first Black/White just wasn't my favorite Pokemon game. But honestly, the unruly fans for the game make me dislike it, almost hate the game(If it wasn't for the cool monsters). Too many fans I know for Black and White come up with endless excuses as to why the lack of lasting appeal is absolutely justified, and act like their opinions are facts and that you aren't entitled to your opinion. Bronies and Mario Fans are more understanding than them, really.
