Warframe is overwhelming when starting it, but it's also incredible to see what it offers in terms of content, all for free (for the cost of grind).
As someone who spent ~3K of hours in it but haven't played it for months, I think it's important to keep in mind how you wanna play it. Don't continue the grind when you feel burned out, not playing a game for a while is fine too.
Edit sorry for the spam, kept giving me errors when replying lol
