Because of course they do!
Well, this is ridiculous. Nintendo of Europe is releasing inferior versions of its retro games on the Wii U Virtual Console. As reported by Eurogamer, the European version of Balloon Fight runs at a refresh rate of 50Hz, rather than the standard 60Hz enjoyed by folks in other regions.
That difference makes for slower games with compressed graphics and borders. Sure, this is nothing new. Back in the day, PAL televisions had slower refresh rates than their NTSC counterparts. While that's no longer the case, Nintendo of Europe continued to release 50Hz games on the Wii's Virtual Console. Why they continue to force our friends across the pond to play lesser versions of classic games is beyond baffling.
Nobody feels nostalgic for slowdown, Nintendo. Nobody.
