>>51180974good new pokemon. and updated movesets mean you can get more use out of stuff compared to gen 4. (for example, I'd never bother with Tangrowth in Platinum but have used it multiple times in Black 2.)
adds useful new items like eviolite and elemental gems.
phenomenon, seasons
and most importantly, the ability to register mulriple items to the Y button. (not to mention registering menus)
the Battle Subway is a more interesting setting than the standard tower, with kickass music to boot.
and cool little touches like the new gym leader music for their last pokemon. speaking of which, the gym leaders are a lot more memorable this time around.
and then in Black 2 you have stuff like the Habitat List and Medal Rally, and Pokestar Studios, side stuff that's fun to do.
is that good enough for you?
