Just started playing it. Played like 2 missions and already felt like I explored more areas than Destinys entire game. Feels a little like destiny. More complicated in terms of how to upgrade stuff, advanced melees, advanced movements. And it's free. Is it any good? Plenty of content? Edit: After like 3 days of playing Warframe I can tell Warframe is better than destiny. Loot system is much better. More content. More variety in pve. Free. Custom mods. Custom appearances. Monthly updates. You can even move your ship during travel. Out of the $500million investment in destiny, bet they only put in $15 on the whole game. (Hyperbolic but still.)
