It’s neat, but the user interface looks like it’s done by an engineer and not a designer. However, it works — only thing I’m missing is the cards other players have bought. They are available, but I’d like to see them displayed up front.
Anyway, the game plays fast and well — the two games I played, I lost both. Let’s see how long it’ll take before I can win, but I’d expect the AI to play well, as St. Petersburg is such an analytical game.
