A rule of thumb I've been following lately (when communicating in e.g. GH issues or Slack messages), is to use the title of the page where possible. Hopefully, the page title should reflect the page's content, and thus automatically works as a link title a lot of the time.

In your example, I would expect the download page of Amaya to be titled "Download Amaya", so my link can simply be "If you are interested, [Download Amaya]!"
