Hello c/Warframe!
First of all, I want to make a big shout out to @keegen@lemmy.zip , whose effort in writing the Weekly Warframe Revisited posts here are what got me back into the game recently.
I just crossed something like 120 hours played (across many different attempts to “get into” the game over the last 10 years), which I know is peanuts compared to many folks, but it’s a significant personal milestone. It’s very rare that any game holds my attention for that amount of time, though full disclosure compels me to state that, prior to this latest interaction with the game, I’d wager I didn’t make it more than 10 hours in any of my previous attempts.
So, thanks to Keegen and their work here. I’ll speak for all of my fellow lurkers (what are they gonna do, post something to correct me? I think it unlikely lol) by saying we appreciate the effort you’ve put into preventing this community from stagnating.
In an effort to contribute, do any of you have any moments you’d like to share where Warframe made you do your best 
?
I’ll go first. Important to note 100+ playtime hours. I JUST discovered this week that the handful of mods I have in my inventory which affect multiple damage stats are rewards for Nightmare Missions. I’ve felt like my main frame’s power level had plateaued for some time, and routinely struggle to take on enemies in the 40-50 range on longer endless missions. Cue me learning that I’d been (intentionally) ignoring the mode which grants the exact sort of reward that breaks a build through to that tier of content, and cue my Picard impression.
Most definitely has to be the first time I realised just how much Endo I’d wasted by selling off duplicate Mods for Creds.
I started grinding weapons before I’d finished the Star Chart, so I had no idea the Index was even a thing. Needed that cash money and had Mods aplenty. Wasted at least about 6 maxed Rivens’ worth of Endo. At the very least, maybe even double that.
And, of course, started floating millions of Credits casually after unlocking the Index. This was slightly worse than buying the blueprint for Orokin Cells from the Market.
Oh, yeah, PSA: do NOT buy resource/component blueprints from the Market! You will literally get hundreds of resources and components by the time you finish the Star Chart!
I was just saying elsewhere in here that I hit my first Endo bottleneck earlier this month and was ruing the mods I had sold for credits over the years. I’m certain it was nowhere near the amount you’re speaking of, but a bummer nonetheless.
Worse was the 7 day credit booster I bought with plat in December because I really wanted to rank up my syndicates.
My first purchase in the game was the spores needed for nova. No regrets.
