The thing about Warframe is it tempts you but doesn’t force you to buy. You can sell your time to people who paid actual money, and then buy things you want for that money. The only issue with Warframe is the fomo - them locking warframes behind relics that are “deprecated”. Sometimes they unearth them again, but it’s an artificial attempt at “I need to buy this or it is gone”.
Also the process of getting parts is 100% gambling on low odds. You can get lucky immediately or have to “reroll” by running the same relic over and over and over again. It sucks if you want a very specific thing and often leads to people just buying it outright.
So no response to “this is impossible, four dudes would need to carry the entire chassis in through a residential door” other than insults. Gotcha.
Extraordinary claims require extraordinary proof. And your story has a huge gaping hole in the middle of it that you cannot explain.
