either you haven't registered or it doesn't exist anymore
THAT A FAKE WEBSITE. no use investing time. They had a web called pokemoncrater but its hack. Do not play online Poke'mon game.
the whole answer is to wait for less players online. you see one map will oveload if over 1,000 players on it i probably would buy a rare map with fewer people.
well really you can go online but anistly i hate Pokemon but i go to school with many kids who like Pokemon so go to Pokemon.com
In what game?
because you cant
Try a google sarch on "pokemon crater" then click on "Pokemon online game {beta 0.1" then just select Signup on the "Signup|login" link.
You can play battle revolution with Pokemon platinum.
for ds you can if you go to battle arena
You are not able to change the lineup in battle arena (battle frontier). What they play is partially strategy as well as you are advised to have tactics in lining. For instance like me, I use Swampert (ground and water) followed by Swellow (not a good flying but can help against Swampert's weakness) and then a Magneton (an extra just in case...).
