Injustice 2 and Street Fighter X Tekken

Hey

Serious question, not trolling, what is the differences between gears in Injustice 2 and gems in Street Fighter x Tekken? With the exception of the latter costing month, both seem very similar and have the same purpose. Yet, no one is complaining about gears. Thanks.

There’s an option to disable Gears on the vs screen

Because Injustice 2 has a gear-less tournament mode.

Gears can be purely an aesthetic once you turn off the stats.
