Seconded. Let’s not bring up playtimes and make anyone feel any sort of way but with over a decade of development, there will be something you can do. You can fish, you can hunt, you can ride a hoverboard, you can dance. Most of those things are just Open world things, but Warframe also has standard randomized tileset missions where premade tiles are laid out by way of some algorithm to make every mission unique while being built out of pieces you can become incredibly familiar with.

Beyond this, now that Cross Play and more importantly, cross save/progression is active you will have so many sweaty vets willing to help you on your platform (the Deck) and from other platforms like switch, PS4/5, and Xbone/Series.

If anyone feels interested in this game, definitely dip your toes and just take it slow. No need to rush things since you can always just take a break and try something else while things are building.
