I don't see any reason to cancel other languages' support, if it pays out for TG, other than "if I can't have it, then they shouldn't too".
I also see no reason to cancel support for other languages. The more so because people pay for the game. However, this decision was taken by the Travian Team, deleting 5 language versions, support and domains. I know that when developing a game there may be mixes of the basic version (German or English) and the national version. However, it does not bother me as much as the liquidation of the entire language version. The community will always help in translations.
I understand the deletion of domains and support. However, I do not understand why it destroys what is already there and what attracts many players - language versions.
As I wrote, facilitating (or rather enabling) language switching will make it easier for many players to play in foreign domains.
I currently play on com, cz, nl, nordic and pl. Only on com I can change the language version. And only on com you can see the flag. Why can not this (version and flag) be done on all servers (domains)?
