Posted more in the Warframe topic currently in gaming, but that game man....
The short of it is that it's completely off-putting for a new player like me, for several reasons.
It might be better than Destiny 2 on a systems level, but at this point I think I'd rather just try Destiny 2 anyway. The analogy I made was that it seems to be like the Diablo III vs. Path of Exile situation.
To make a point: the current EVE Online tutorial, which still isn't very good mind you, is better than what I experienced in Warframe's first few hours.
Maybe I've changed, but I don't think I should have to feel like I need to watch tutorial videos/streams and/or read a wiki within the first couple hours of gameplay, even for an extremely dense game. That's just not good design, and even if it's intentional to an extent - the marketing/general air about the game doesn't radiate that.
My problem is that it's not really built for solo play, so it's easy to get overwhelmed by enemies. And when you play with others they're mostly just speedrunning so you can't get a lot of mods and loot because they just want to get through it fast.
Also, the bombard and aerial enemies are assholes.
That isn't to say it isn't fun, but it feels like once Destiny 2 comes out I'll probably drop it like a hot potato, at elast for a while.
