Per game though rather than pay company, so you can't get around that by setting up multiple companies. And if companies want to leave because they feel the "tax" is too high, then I do think that suggests the 70/30 split isn't working. And it's definitely not okay to bend over for the bigger companies by reducing the split as they sell more, and screwing over Indies who don't have the clout to complain. I know a lot of people hate EGS here, but there's a good reason so many devs are getting behind that store.Well the tax comparisons run reasonably deep here if you want to take them in that direction but of course every analogy has it's limits. Like in real life it's common to set up shop in other countries to dodge taxes, while in gaming it's more like "founding a new country to avoid paying taxes".
Steam starting at an 80/20 split and then getting worse for more successful games would drive large companies away, which is the exact opposite of what they were aiming for. They want to slow the bleeding of AAA games leaving the platform for publisher exclusive ecosystems. You've had EA leave, Bethesda flirt with leaving (this new revenue system may have been what convinced them to stay), Activision pulling it's biggest franchises off, and now uPlay leaving for epic deals (I maintain that this relationship will be turfed in the next 24 months for pure uPlay exclusivity on all major Ubisoft franchises).
It's not "fair" in a social mobility sense, but neither is any form of bulk discounts, corporate contract discounts, or other things that are only avilable to the well off.
Maybe 80/20 starting split, reducing to 75/25 after certain sales figures are met, is the middle ground here. Heck, any kind of movement would be appreciated, even if it's a flat 75/25. And I mean from all stores there, not just Steam.
