I have put 500+ hours into both games and i must say warframe all the way with modern destiny i can get to level 34 in a week end but in warframe i can chose what i want to do, go, build and play if i want to play as a new warframe i can easily go out and farm for it once i have it i can build it and then play was that warframe, each warframe has 4 abilitys what just feels so much more than a grenade a super and a melee at the end of the day both are ok games but warframe just has soooo much more content and for free! that i would much rather play it. also SARYN FOR THE WIN!!!
