What is the difference between が（suru-verb）できる and を（suru-verb）できる?


For example, what's the difference between the following sentences?

> ゲームで勝つことで、ポイントを獲得できる。  
>  ゲームで勝つことで、ポイントが獲得できる。

Intuitively, I felt like the first sentence sounded better and [example
sentences](https://yourei.jp/%E7%8D%B2%E5%BE%97%E3%81%A7%E3%81%8D%E3%82%8B)
seem to back that up. What's the difference between using を and が with a する
verb (in potential form)? If both are alright, and when does one sound more
natural than the other?

I have seen [this post](https://japanese.stackexchange.com/questions/609/the-
difference-between-%E3%81%8C-and-%E3%82%92-with-the-potential-form-of-a-verb)
as well, does the same thing apply here?
