How difficult it is to translate a game (HA for example)
in other languages ? I'd like to see if I can do it for
Greek from example...

A new translation is a long work because each scene should be modified. But if a new language is wanted by many people, it's possible to do it.

Shark, there is always the possibility to import texts from an external file (on your website) inside a Flash movie. Implemented like this new languages can be added even after a game gets published. The opening page could read the possible languages (from a ini file) and put these in a drop down box to choose from.
O course it is nearly impossible to upgrade old games, but for the new ones...

Downloaded versions (exe) could have language packs...

I should have mentioned it before, but if you ever need another Spanish translator, just give me a yell, Shark...

Thx
I will remember it

Yep, and me for Dutch...
