in my opinion you should focus your efforts on countries you manage to find someone IN THE BUSINESS to work with you full time. Getting translation is easy but if its not done by gaming people you will usually end up with really bad quality, in which case your visitors usually would prefer English.
Don’t translate 1 page to 20 languages, I think its correct to choose 1-2 languages and stick to them, translate many pages targeting many different keywords. Language specific keyword research is very important to do before you dive in.
My 2 cents
