During his GDC panel, "One Man, 17 SKUs: Shipping on Every Platform at Once," Retro City Rampage creator Brian Provinciano provided a clear breakdown of the game's fiscal performance across various platforms.

PSN was where Provinciano saw most of his profit come in: over $600,000 earned across over 35,000 units sold on PSN. These numbers do not account for PlayStation Plus downloads and the period of time during which RCR was offered for free with membership.

The PC platform yielded the second-highest revenue for Retro City Rampage, earning over $400,000 from over 40,000 copies sold – the majority sold on Steam. Xbox Live Arcade came third with around $200,000 earned across 15,000 units sold, and WiiWare earned under $10,000 with fewer than 2,000 units sold. After the panel, Provinciano told me sales currently sit around 97,000 total, and that he anticipates total sales will exceed 100,000 next week.

Provinciano said he spent the most development time on the Xbox Live Arcade port, on a platform he called the most expensive. "Knowing what I know now, I would've skipped it," he said. Though he considered the WiiWare version a $20,000 gift to fans, the XBLA port ended up costing more.

Update: Brian got in touch to tell us some of the numbers in his panel were a bit off thanks to an Excel issue. "Looks like Excel didn't line up the bars up correctly." The WiiWare version sold under 2,000 units, he tells us. "It's also sold significantly more than 35K on PSN, 40K on PC and 15K units on each of the other platforms."
