Creating launcher codes or whatever to intentionally create separate communities will be counter productive. If we start doing that, we would have to do it for every known language on the planet. I am sure no one here thinks their race is superior to another....... Well, you might, but that bullshit stays out of this forum.
This mod was created in English and that is the only reason it is that way. The mod is English, the sky is blue.
1. adding language plug-ins wouldn't take much effort. You know all other major mods have already done that, and the localization is always community driven, and there will be volunteers like @saukopf to help accomplish this, and make a mod more globalized. it's nothing like making separate launchers to separate players speaking different languages. It's all the same launcher, all function the same, ppl are joining the same game lobby and playing the same game.
2. it's not about only chinese. as i mentioned, all major mods support multilingual. It creates solid player base, make more COH players all over the world to enjoy the mods, and enjoy playing with each other.
3. never underestimate enthusiastic fans, they could get the job done very professionally, if you open the port (multilingo plugin support), give them the chance (recruit them as volunteer translator). take @saukopf for example, he is the chinese translator (mandarin or/and traditional chinese) doing official localization for almost all major mods. he's a perfectionist, and has all jobs perfectly done.
4. everyone knows EIR has a big learning curve at the beginning, even you are a native english speaker, you still need some time to learn how to register CP, how to manage your company in the launcher, and most importantly, how different the game mechanic is comparing to vanilla COH and all other traditional MP mods. the interface with a player's native language will definitely make this much easier for non-english speaking players or players with little english skill.
5. ingame communication is not something too serious to worry about. most players comes from vanilla COH and have already played hundreds of games on relic MP server, they have survived and won't do any worse in EIR. players like this will try their ass off to be as much communicative as possible with their very limited english skill. at least they've learn something very basic in order to play coop. In the worst case, for ppl who don't speak english at all, they will goup their mates together as your opponent, except for some basic greetings, you don't have to discuss tactics with them, do you? just don't laugh at their poor english, they will respect you as much as you respect them.
6. asking for multilingual support is just one simple wish. dev team can take as much time as needed to finish that. anyone discuss this matter in this thread is more than capable playing EIR in english, they are also very communicative in english, have absolutely no problem with a english-only client. it's just we care our fellow friends who eager to play EIR, but have difficulty on getting involved due to the limitation of their language skills.
7. for the long run, except EIR team wants to keep the community small, enabling multilingual (meaning on the client side, launcher interface) is a logical and necessary move for EIR's future development.
that's only my personal opinion
