Great job! I would recommend several modifications:

1. Move kruise-game from experimental/addons to addons. Let's make it an official one.
2. The workflow step should use the deploy step. apply-component step you used here cannot make multicluster deploy effective.
3. The helm chart version should be extracted as a standalone parameter in parameter.cue.
4. Do not embed kruise directly in the kruise-game addon. Leverage the existing kruise addon.
5. Add the resource relation below.

apiVersion: v1
kind: ConfigMap
metadata:
  labels:
    rules.oam.dev/resource-format: yaml
    rules.oam.dev/resources: "true"
  name: game-server-set-relation
data:
  rules: |-
    - parentResourceType:
        group: game.kruise.io
        kind: GameServerSet
      childrenResourceType:
        - apiVersion: apps.kruise.io/v1beta1
          kind: StatefulSet
        - apiVersion: game.kruise.io/v1alpha1
          kind: GameServer
    - parentResourceType:
        group: apps.kruise.io
        kind: StatefulSet
      childrenResourceType:
        - apiVersion: v1
          kind: Pod

It looks good. I will later validate it again in multicluster scenario. There is some trouble with CI because it depends on Kruise but Kruise is in the experimental part. So I guess we need to make it an experimental one for now. Then we can move both kruise and kruise-game from the experimental to the official folders.

Great job! BTW, you can add topology for other addons if you'd like to. Thanks!
