Are there many pc games inside the indie branch which dliver Arabic, especially at those games, which were developed by one person ?

I understand that some players prefer to play games in their native tongue. But I also believe that asking nicely (and, ideally, offering help) has a much higher chance of improving the situation than grumpy remarks.

Many indie games include translations made by volunteers from the community. This approach often works very well, and is a win-win for both the developer and the players. If you want to play indie games in Arabic, then (in my opinion) the best of course of action is to try and connect developers with people who are capable and willing to translate from English to Arabic.
