Xbox Game Pass in Costa Rica

No they are not

Costa Rica doesn't even have Xbox consoles officially

There is no guarantee cloud support or consoles will ever come to Costa Rica. Accessing services not supported by your region can lead to account and hardware bans

Costa Rica isn't on the list, but hopefully they add it soon.

hello, you can check this link http://www.xbox.com/en-US/games/xbox-game-pass. under the FAQ section.

Costa Rica isn´t in the description but, It seems like they will be continuously adding new locations.

I understand. I was suspecting that Costa Rica is not a supported country because is not on the list.

Well, i believe i will need to wait for my return or hope that Costa Rica will be added to the list of supported countries.

I think game are region in coded and if it was bought in Canada it won't work in Costa Rica
