Encounter rate is
horribad. At least my smug snake guy always had enough speed to allow for a near-100% escape rate or I'd have gone insane. Caves are now filled with OHKO-resistant monsters. Yes, no more randomly exploding stone things, now they just survive your attack and bash you around for a bit. Get that always-escape holding item or a billion Super Repels unless you want to play until your grandkids reach college. TMs are now re-usable. HMs are virtually unneeded for story progression and only really required for optional stuff. Music is quite impressive, considering the atrophied DS soundsystem.
If I had to put it into one word, what I feel is missing from White is customisability.
Things you could do whenever you were burned out from battling all those mons all the time - without being unproductive. In Pearl there was the ill-conceived yet nonetheless enjoyable underground, and the pokeball seals, and the apps for the lower screen, and so on. The two uses of the lower screen in White: Y-down-Y for treasure radar, or mash right side with thumb twice for quick-save and music. The rest is online-related and as of now absolutely useless.

It's a shame about... well,
all of the online stuff. Nothing works on the first try, if at all. I doubt Nintendo will have fixed their single V92 Modem in the Wii server pool before I lose interest. I know they're probably a
teensy bit busy fighting off the radioactive mutants creeping out of the quake rifts in their basements, so I can't really bitch too loudly, but still, this irks me. This is a huge company, 2011, and a multi-billion dollar franchise. Server capacity and bandwidth are comparatively cheap and effortlessly acquired.
Meh. It's Nintendo. A-hyuck.

Oh yeah. There's a honest-to-god attempt at storytelling.

It's all hippy Pokelovers vs civilized world with some heavily telegraphed twists, but hey, it's better than THAR BE MONS HUNT DERP. This was really surprising, but much appreciated.
