Hey everyone! Old school Pokemon fan trying to get back into the games. The last games I played were Fire Red & Leaf Green for Advance SP. I don't know any Pokemon outside the first 251, so I'm excited to jump in & see how much its expanded! Anyways, I'm taking the hit today and heading to Game Stop to buy a used DS. I was told I should def invest in Black 2 or White 2. Suggestions? Why should I choose one over the other? Anything to help me out would be AWESOME! Thank you!
Let's see if I can sort some of this out for you.
B/W and B2/W2 have generally the same wild Unova Pokémon exclusive to them; for instance, Gothita is in B/B2 and Solosis in W/W2. So research Unova exclusives and decide what you like. You may prefer B2/W2 with past generation Pokémon in the wild everywhere, not just in eastern Unova.
B/W2 allow you to catch Reshiram. W/B2 allow you to catch Zekrom.
B/W allow Tornadus (B only)/Thundurus (W only)/Landorus (must have both) to be caught in-game. B2/W2 allow all three as well, but in Therian form and you must use Dream Radar (a separate application) if you don't want to trade for them.
Cobalion/Virizion/Terrakion can all be caught; in B2/W2 they appear in front of you starting with Cobalion at Route 13. Terrakion comes out after you defeat the final Gym; I don't recall seeing it before clearing all eight Gyms. In B/W, you must seek their chambers, two of which can be found in B2/W2 as well (but are empty).
Liberty Garden Victini is event-only in B/W. Event has passed. You can technically Action Replay the item into your game, but some see this as cheating even though it's an expired event. You can still trade for many other Victini events, however.
Finally, Kyurem is available in all four games. The final three after it (Keldeo/Meloetta/Genesect) are exclusively events.
B2/W2 feature a lot of past legendaries; for instance, Cresselia and the Lake Guardians appear post-E4, as does either Latios or Latias. Also, the Golems put in an eventual appearance post-E4. Deoxys is a CURRENT EVENT. Heatran appears at Reversal Mountain. If you like getting legendaries, get either B2/W2, but use the exclusives in each game (such as Reshiram in W2, Zekrom in B2) to decide what you prefer. I chose Black for Reshiram, myself, and got W2 because I wanted to change colours.
