...or you can go all the way, skipping reset! completely:
(swap! game-objects (fn [objects] (reduce-kv #(assoc % %2 (update-object
%3)) {} objects) ))

ps: I've not tested this but i don't see why this approach wouldn't work...

use reduce-kv on the original map to save some intermediate vector
allocation...something similar has come up recently...
(reduce-kv #(assoc % %2 (update-object %3)) {} @game-objects)

I'm updating a set of objects stored in a map, and I feel like the
way I'm doing it right now is inefficient. Is there a better way?
(defn update-all-objects

(reset! *game-objects*
(into {}
(for [[k v] @*game-objects*]
[k (update-object v)]))))
