Hello Italian player here.
About the language issue is in part real, considering a small % of italian players use the Italian pack (even if the translation are really bad and funny).
Most of the veterans know already the game well and don't need to put it in Italian.
Considering you want to have as much as possible players inside,and forcing them to play in English could be an issue, it's also real that the % of those players are really small.
I beleve nothing need to be rushed but putting online the server in English and informing that "later on" there will be the correct language pack shoudn't be an issue.
I'm glad that an EU server will be open, Germans servers are one of the best there shoudn't be any ping problems.
I'm pretty sure a lot of players will join, because atm the situation on the Gameforge side is pretty bad and a 4.6 patch will bring back a lot of nostalgic players.
One thing i'm concerned is the camera issue, for windows 10 user, could be great to fix it permanently without your fix that require to deactivate completely the anti virus and that's could lead to frustration and people not joining in.Especially for non techy players
Good luck, i opened a post on Reddit but so far no response about the language pack.
Thanks for your work and sorry for any grammar mistakes
