I really like the Pokemon in the gen, but if I may say so, the games are probably the least satisfying in the title since Red/Blue. Pretty much all you get to do in the game is battle. You don't get a casino or a safari zone or ANYTHING. ...Oh yeah, there's Pokemon Musical, but it sucks. So basically, if you want to find something different and fun, you're pretty much FORCED to "get creative." Never should you have to "get creative" in order to find fun.
I know what you're going to say in that battling is the main focus of Pokemon. Well, yes and no. What made Emerald/Platinum/HGSS so fun wasn't the battling aspects, but the amount of fun things you could do BESIDES battling. Stuff like the Pokemon Contests, the Secret Bases, Battle Frontier, Super Contests, Pokemon Underground, Pokeathelon, and that's not even counting all the little things you could do like grow berries and collect soot.
In Black/White, all the stuff that made the past few games fun is now limited to "online only" content. Growing berries? You can only do it online. Secret Bases? Online only. And so on. And for me, stuff you can only do online might as well not even exist, because I'll never be able to go online on my DS. To get WiFi on my DS would require serious re-working to the router, and I don't go to any WiFi hot-spots except for McDonalds, and I've NEVER gotten it to work there either.
And before you say "People without Wifi are a dying breed," no. That's not an excuse. That's an AWFUL excuse. Even with the number of people that have WiFi over those that don't, limiting content to Online Only is STILL limiting those that can use it. In-Game content is NOT limiting, because EVERYONE can use it.
So, yeah. If you have WiFi, you might like it. If not, stick to Platinum or HGSS. And the worst part is... It looks like they're BARELY going to address this problem in B2/W2. Pokemon World Tournament? Big deal! PokeWood? Whatever. Medal System? Forces you to get creative. I swear, if they ever remake Ruby/Sapphire, and they get rid of secret bases, Battle Frontiers, and Super Contests, and limit it all to Online Only, I am going to be super POed.
