English-speaking population is about 1.5 billion worldwide and 300 million of that is in the US (first language or additional language), so the US is about 20% of the world’s English speakers. The 2nd and 3rd countries with the most English-speakers are India and Nigeria, so factor in internet access, and the US is almost certainly >20% of the English-speaking internet.

One of my main tools has been SteamDB’s instant search - it’s basically a giant list of all steam games, sorted by review score, with a TON of different filters you can apply. Looking specifically for something released this year? You can filter for it. Looking specifically for a co-op action shooter, or a singleplayer 2d platformer? You can filter for those too. Wanting to exclude early access games or exclude games with a min/max number of reviews? You can do that too. Very handy tool
