there isn't one in which you can interact with other players.
at this moment there are none but Digimon World online is under development
yes there is 2 MMORPG Digimon games, Digimon Battle online and Digimon Masters online. Digimon Masters has more people on it but suffers from slight lag But both brilliant games (in my opinion)
Digimon Battle At [Link moved to related links - Admin]
There are plenty of games on BYOND...Like Digimon Wild

jetix.com
You can play it on a online games website.
there is a digimon online game here but you will not be able to play it until 17th march 2010.if you join now you will get a special pack (not advertising just mentioning) it is here at http://digimonbattle.wemade.net/main/main.asp.

it depends on what you are playing but in online games its 71 and in usual games its 70 of rizegreymon
You can get digimon world dawn or dusk at gamestop or any store with games. If you can't get it at the stores you can play it online.
