Hello, good night.
I'm a little confused about the Houdini Indie license showed on Steam:
I'm looking into renting Houdini, the Indie version specifically, and I found this on Steam:
What does that means?. Is it gonna be 351.99 PER month after one year if I take that first option?
This appears to be a typo on Steam, thanks for pointing it out. I will contact Valve about fixing it. Houdini Indie on Steam is billed on a annual basis, monthly billing is not currently available. So you will be billed the full price of Houdini Indie when you purchase and then billed annually when the license renews.
