y'know
what would've helped is if you linked to those things instead of just typing them
that way it'd be easier to show
i have pokemon black, and i am enjoying it. i think that most of the better version exclusives (the green psychic jelly babby :3) are in white, but i'm not sure of all the differences.
http://serebii.net/ should have all the info you'd ever want on the games, their differences.. oh yeah. they've got you covered and then some.

they're not all stellar, but they're alright once you spend some time with them.
reminds me far too much of digimon, though.. but could just be me.
i'd say get it if you're interested, and if it's on sale. some places did that when it was released.. dunno about now.
oh, and a heads up: unless you have a DSi, there's a good chance you won't be able to use wifi/connect to the internet. the main things that matter that you'd be missing would be the dream world/game sync (dunno exactly what that is), global trade station, and wifi battles.. but the main game is still there, totally playable if you have a friend that has it. just don't go hoping for internet.. unless you have a DSi. in which case, go nuts.
