So you remember that when Warframe first came out it was just a simulator of running through blurry corridors without textures. (and without content other than enemies)

Anthem will do fine if they are allowed to support the game for at least a couple of years, they are more than capable of keeping the fun ball rolling.
And yes, btw. I agree Warframe is a horrible grind once you've passed the friendly starting bit.

Anthem, on the other hand, seems quite alright in that regard. The missions are well-narrated and keep you going (well, me, anyway), crafting is not grind-heavy at all. In fact, playing on hard difficulty, I have enough resources just from dismantling the tonnes of gear and guns I loot. I have yet to venture to Free play in need of "grinding some mats".
We'll see how it goes. I love it, so far.
(oh and that last bit - that was meant as a joke, of course. A slight poke at Warframe where you can literally buy everything, while people are bashing Anthem on MTXs for having six cosmetic items in the store.
