The “gaming dual media approach” in blogging usually means covering games using two content formats together, like written articles (guides, reviews, news) plus visual content (YouTube videos, shorts, or clips). The idea is simple: some people prefer reading, others prefer watching, so you reach both audiences and even cross-promote (embed videos in blogs, link blogs in video descriptions). I’ve seen this work well because a quick video grabs attention, while the blog gives deeper info and helps with SEO traffic.
