Show HN: Text Battle – AI-simulated fights, daily leagues (Elo Ranking)
2 points by sungchi 419 days ago
I built Text Battle, a lightweight web game where you:

- Write a character prompt in ≤ 100 chars (e.g. "A sarcastic cyber-ninja with a plasma katana").

- Earn Elo and appear in daily or unlimited-season leagues.

Feedback I’m looking for:

- Whether the 60 s cooldown feels fair vs. annoying.

- Balance of Elo gains between free and paid matches.

- I added micro-transactions because LLM costs are non-trivial; any tips on model/infra optimization to keep it free-to-play are welcome.
