>>47382641>Will it have soul even if offline?Yeah, they're really good games.
>Will I be missing much since the Wi-Fi was shut down.No, but for what it's worth there is a fan hosted GTS that will allow you to trade with others, and also collect mystery gifts and special Pokemon at random. So I think it'll be fine, unless you're emulating, in which case you aren't missing much.

>>47382656 said, I think Gen 6 wonder trades and PSS is the best and most relevant online has ever been and I wish I engaged with it more back in the day but I was hating on Gen 6 for getting more attention than Gen 5 even though I thought the story was worse and it should be vice versa. I also didn't like Mega Pokemon iirc, but I like them now. I'm not a Gen 5 fag anymore though so I think you'll probably have the most fun with Sinnoh and Johto, but if I'm wrong, I'm wrong. BW is still good, I just sort of think it's not as great as I recall.
