Steam for Linux is mixed 32/64, unfortunately the main executable (~/.local/share/Steam/ubuntu12_32/steam) and its associated steamclient library continues to be 32-bit only and runs with a couple of horribly dated libraries in the mix. That process does pretty much everything aside from the UI.
Dual nominations for Paper Mario: Sticker Star & Paper Mario: Color Splash. The only thing I really remember about them is that I played them and they left me without any feelings about them whatsoever.
