Several Questions the 5th Gen Game

3. Just to elaborate, Dream World is browser based "game" that's similar to the secret base aspect of RSE. You can collect furniture and arrange them in your room as well as visit your friends' bases. You can also play mini games, and I THINK that when you win random events can happen, including meeting a pokemon. The pokemon if male, has special moves that can't normally or easily be acquire (ie. TM or Egg moves). If female, the pokemon will have a dream world ability. Also, the dream world is the only way to grow berries in 5th gen.

Dream world is part of the global link, which also incorporates GTS, the battle union and miscellaneous DLC. Some people are also think that unity tower is going to have something to do with with the global link as well.

EDIT:
5. Just to clarify, you are able to go into your friends game to visit Black city/White forest via local wireless. You can also do "quests" and whatnot that involve you traveling your friend's Unova region. It's called the Entralink

Thanks hurricane and jinn for your answers. Cookies for you two as well!

So dream world is done on the computer? Not the DS itself? (I mean after the hook up to the global site)

Also getting different mixed answers about 5....Jinn are you saying that I can do 'quests' in the area (for example, black's city), but I won't be able to buy items or battle the trainers there? I looked up entralink, but it sorta confused me...

Man pokemon got a bit more complicated in the years I haven't played...
