LootLocker has SDKs for Unity, Unreal, Godot. If you're building in MonoGame or a plain C# project, you're on your own.

I ran into this myself while working on Edin's Gate. Wiring raw HTTP calls to a backend you didn't build gets old fast. So I built a wrapper and figured someone else might need it too 😊. What I covered 🔥

Auth: guest sessions with automatic player identity persistence, Steam login. Player: profile info, display name, server-side key-value storage. Commerce: currencies, wallets, balances, catalog browsing, credit and debit. Leaderboards: submit scores, fetch rankings, member lookup, full metadata Progressions: XP systems, battle passes, skill trees. Triggers: achievement-style reward firing, single and batch.

How it's built 🧠

Three .cs files. .NET 8, System.Text.Json, no Newtonsoft. Single static HttpClient. CancellationToken on every async method. Full XML docs & IntelliSense on everything.

Comes with a README and a working MonoGame demo project 💯 V2 is already planned — Characters & Heroes, real money purchases, additional auth providers. Existing buyers get it at no extra cost 🔥.

If you're building a game in C# and need a backend that just works, this might save you a few days.
