Back in the early days of recorded gameplay there was a massive influx of gaming VODs to Vimeo, because they were basically the only mainstream video hosting site that had good enough quality. Iirc Vimeo even had to ban gameplay videos.
Many games were not viable on OnLive, some because of latency and some because of fuzzy image quality. It was a good service for the super-casual gamer. But those all play games on their phones now.
