Uh, you may not be able to directly elect a government, but you still elect the parliament which then chooses the government. So yes, you have a say in it, by casting your vote in the parliamentary elections for the party you want to see in government.

And yes regarding Germany: Germans vote for parties in a parliamentary election; in the parliament a party or coalition of parties who can get the necessary majority votes will elect the Chancellor (head of government), who then is formally appointed by the President. The Chancellor then proposes cabinet members who are formally appointed by the President.
