I'm on PS4. Yeah the game is tough to get into cause of that steep learning curve and lack of in-game tutorials. The way I got over was setting specific goals and reaching out for help from my friend who has been playing for a long time. Some goals were, today I'm gonna finish mars, tomorrow earth etc. Then it was unlocking the relays. Then after that you start unlocking story missions etc and before you know it your on your way for building more frames, getting prime parts and learning how to navigate the trade chat. Lukily the warframe community is pretty helpful when I was first started out to get me over the hump.
