Desolation Giant destroy all other creatures you control. If it was kicked ruling

[Ninja]

if i play Desolation Giant and I pay kicker,

it says:

When Desolation Giant enters the battlefield, destroy all other creatures you control. If it was kicked, destroy all other creatures instead.

for the kicker does it mean:

"destroy other creatures other then the creatures you control" (so my other creatures live)

or just it means to destroy all other creatures (so my other creatures die)

its not so clear because of the "instead" and the 1st condition

[Arix]

By "all other creatures", it means "all creatures except for Desolation Giant", so everything else dies.
