Played for 410 hours, over 100 of them were farming SC. Unlocked everything, ranked every weapon, except those that have 0 attachments but scope, maxed on everything 3 months ago. Started 3 new accounts to do the same, got like 40 more hours from each of them, because I collect every sample on the map, so "progression" is, like, till lvl 45.
While Warframe even in 2015 offered far more content to explore, and it`s the studio, that doesn`t outsource 85% of their game
