We launched an indie game last year, and one lesson we learned was that the affiliate network itself wasn't the biggest factor—the quality of the affiliates was. We ended up using Impact because it was easy to manage, but most of our sales came from a handful of gaming YouTubers who genuinely enjoyed the game. If you haven't already, prepare a media kit with gameplay footage, screenshots, banners, and a clear commission structure. It makes it much easier for affiliates to promote your game.
