第 3 层 · 内容

AI-native + 手做

AI-native：vision 看你的物品、gen-image 出关于你的画面、LLM 写关于你的台词。

手做：每个游戏有作者声音。不是 procedural slop。混合 register：After Dark 黑色 FMV、sensory toys、action、daily collectibles 都能并存。

第 4 层 · 社交

Feed-as-verb

浏览 ≠ 点赞。动别人内容 → 推作者。

已成型 pattern：
· score_beat: "你被 @xxx 超了"
· kept your stone (Pebble Pocket)
· kissed your portrait (Kiss Wall)
· marked your card (Daily Arcana)
· cross-game notify chain

👉 关键判断题：当你给 AlterU 设计一个新游戏的时候，问自己—— "这个游戏的身份层在哪里、内容层是 AI 写的还是手做的、社交动词是什么？" 答不出来 → 它就是个普通 mini-game，不是 AlterU 游戏。

Layer 3 · Content

AI-native + hand-made

AI-native: vision sees your stuff, gen-image renders pictures of you, LLM writes lines about you.

Hand-made: every game has an author voice. Never procedural slop. Mixed register: After Dark noir FMV, sensory toys, action, daily collectibles — all sit side by side in the feed.

Layer 4 · Social

Feed-as-verb

Browsing ≠ tapping ♥. Touch someone's content → notify them.

Shipped patterns:
· score_beat: "You just got passed by @xxx"
· kept your stone (Pebble Pocket)
· kissed your portrait (Kiss Wall)
· marked your card (Daily Arcana)
· cross-game notify chains

👉 The litmus test: when you pitch a new AlterU game, you should be able to answer — "Where's the identity hook? Is the content AI-written or hand-crafted? What's the social verb?" If you can't, it's just a mini-game, not an AlterU game.
