Easy question: chainring compatibility

Is BCD the *only* determinant of chainring/crank compatibility?

I'd like to buy a new chainring for my bike. The current one is 130 BCD, 3/32. Will *any* 130 BCD, 3/32 chainring fit?

This is for a fixed gear, so I know chainline can be an issue. AFAIK chainrings don't alter chainline, excepting for inside or outside attachment to the crank arm. Let me know if there's something else I need to think about here.

Thanks!
