73%? I'm sorry, I think you may have failed to realize the massive size difference between Destiny's total average playerbase and Warframes. Just a reminder, Warframe has about a third (or less) of total average playerbase, even after Destiny's been dwindling. Warframe is one of the least played free MMOs, even Neverwinter has a larger playerbase than it, so of course Warframe's retention rate is going to be higher. You want to also know why Warframes is higher? Because it's mostly people that [b]pay hundreds of real life money for their gear so that they don't have to grind 50,000 hours to get the absolute best gear and most broken frames.[/b] Please, continue to pump out more biased and uneducated information.
