Steam is something I still have installed on my phone but it is only something that I use when I need to if the game I wish to play is only on Steam. I think the last time I used Steam it was to play World Boss in the which is in early access.
Yes, I'm a PC gamer apart from PS5, so Steam is the place to go when I'm looking for video games at a good price for PC, Steam has taken over the majority of the market in terms of computer games, so using it is convenient.
