over 100 hours in, Rage quit twice, farmed 8 hours straight for ♥♥♥♥♥♥♥♥ Oberon; got him yesterday.
Went into the game for an hour a day play, ended up playing almost every day since August.
9/10. Damn Oberon Blueprint spawn rate....

Update after 3 years still playing:
Holy heckers guys. This game... While it makes me rage, it makes me cry, it makes me laugh and die. This game is better than anything you could ever expect. It's an arse to new players because it just drops you into things; but stay with it! The rewards are better than any kind of AAA game, for FREE. Digital Extremes have made a game that I can honestly say is now like a child to me. I don't want any harm to come to it, and I love it so much!

Third update: Since we're just before the launch of Empyrean, its important to note that there is a lot of complaining, particularly from newer players about the difficulty level of warframe, and that the grind is too hard. what the heck people!? this game is free, it doesn't ask for a single penny, the developers treat it like their own child, the community loves it, why are you complaining? All of us older players understand your frustrations, but that's exactly why we love it so much, because of the payoff you get, the pure happiness when you finally get that warframe you've been itching for, that kubrow that is too adorable, anything. And things just keep getting better from there. My advice? Stick with it, it is an absolute pain for new players but heck is it worth it!
