I think Warframe is the only (non-open source) free to play game I have nice things to say about.

I never felt any pressure to pay, but every few months of playing and I would think, “I feel like I should chip these folks some cash, again”.

And then they do make it fun to chuck them some money.

Most of the purchasables may as well just say “trust us, it’s fun”, for all I understood any of them before buying. (I think I bought maybe 4 frames while playing for about a year.)

After playing for awhile, I do trust them. I’ve not been disappointed with any purchased frame or item - with the understanding that both are pretty much just amusing “thank you” gimmicks for supporting.

Warframe has been a good time. I sort of expect it to enshitify at any moment, but for now they seem chill.
