Help to translate a tweet: よりも, 可能なところ, みな, 数十手先


I'm trying to translate a tweet from a Japanese account but I'm not able. I
know almost all the words, but can't understand the sense.

My Japanese teacher didn't understand it very well neither and she couldn't
give me a correct translation into my language (Spanish).

> ゲーム業界のパイの喰い合いに本気出す **よりも** 、 **可能なところ**
> はみんなで人類みなゲーマー目指したほうがハッピーだと思うけど、最終的にその世界人口にも限りはあるから **数十手先**
> まで関連する以上何が正しいか判断付かない。

These are the main problems I have (but not the only):

  * What does よりも mean here?
  * 可能なところ: Possible place?
  * Is みな the same as みんな?
  * I think 数十手先 is any kind of chess term, but I'm not sure.

My translation:

> More than getting serious on eating together the pie of the games industry,
> I think the possible place is all the humanity trying to be a gamer to be
> happy, but finally, as there are limits for the population of that world,
> there's no correct relationship more than see ten turns ahead




**Context:** The person who said this works in the game industry, and this is
a comment on a certain Japanese pro-gaming team that apparently is in trouble.
Sadly, professional gaming is not yet widely recognized in Japan.

* * *

  * ～するよりも means "(rather) than doing ～"
  * 人類みなゲーマー is a parody of a famous phrase 人類みな兄弟 ("All human beings are siblings"). みな is, yes, みんな. So 人類みなゲーマー(を)目指す literally means to try to achieve the everyone-is-a-gamer situation.
  * 数十手先 is a chess/go/shogi term. "(what happens in) several dozens of moves ahead".
  * 可能なところは in this context means "where possible". It means either 可能な会社 (companies that may try to achieve 人類みなゲーマー) or 可能な分野 (fields where people can try to achieve 人類みなゲーマー).
  * This `verb + 以上` is not "more than" but a conjunction meaning "since ～" or "so long as ～". See [this](http://www.jgram.org/pages/viewOne.php?tagE=ijou).

I think I understand what this guy is trying to say, but the following
"translation" may be very rough due to my limited English skill.

> ゲーム業界のパイの喰い合いに本気出すよりも、  
>  Rather than scrambling for a piece of the game industry pie,

→ Rather than competing hard in the existing game industry,

> 可能なところはみんなで人類みなゲーマー目指したほうがハッピーだと思う  
>  wherever possible, I think it's happier to strive together for the world
> where everyone is a gamer.

→ if the situation permits, it's probably better to try to increase the number
of gamers itself.

> けど、最終的にその世界人口にも限りはあるから  
>  However, ultimately, there is a limit to the world population,  
>  数十手先まで関連する以上何が正しいか判断付かない。  
>  and since things in dozens of moves ahead are concerned, I cannot judge
> what is correct.

→ But the number of potential/future gamers are limited anyway, and you cannot
expand the game market forever. Since predicting the long-term future is very
difficult, I don't know what is the correct strategy.
