Would it be okay to buy Pokemon Black2/White2 if you haven't played the first one(s)?

Pokemon Black/White 2 is a continuation of Black/White 1. It would make madami sense if you played the first ones before the segundo ones, but it doesn't really matter. there are different gyms, and different things happening. The only similarity is that the enemies have the same name as the Black/White 1 enemies, yet they are very different. After a bit, you will know exactly what's going on. XD

Sure! If you wanna buy Black2 or White2, go for it :D
If you ask me, I think the 2nd version is better :P

Yes, but I'm stuck in the Pokemon Ranch! Can anybody give me some tips on how to ilipat on to the susunod city?

Well you can.. but you will understand and enjoy the game madami if you played the first game. You can definitely buy them, I'm sure you'll catch on.. but the game will be madami enjoyable if you played the first!

Eh I don't think it really matters either way..it's not like the games are meant to be played in order you should choose whichever you feel most comfortable with first.

I suggest you play black and white 2, it can get quite annoying as if your slightly repeating the same moments and trust me I ABSOLUTELY HATE that. You get easily frustrated and since it is the new(er) release, this may be a tad madami easier and madami fun to roam around a bigger, better region and explore madami stuff with your loved companions and have those *special* moments with those allies who adore traveling with you.
As you venture on your journey you can obtain madami pokemon, discover madami tactics and perhaps experience the heart-thrilling events caused sa pamamagitan ng the awesome, deadly TEAMPLASMA, just like plasmapeople said, there back and better than ever!!!!!!!!!!!!!
Yes Black and White 2 may be 'bizarre' at first but once you get used to it, BE READY FOR A GAME THAT WILL ROCK YOUR LIFE!!!!!
Well that is what I think
