Could anyone ever keep up with the game releases of any successful platform?
The PS2 had thousands of games, hundreds of solid games, and yet I only managed to play 200 give or take including crappy ones. No one is ever going to play every good game. The best consoles have a tie ratio of 10-17~. Per console unit, this is just 11-17 games sold, out of thousands available. But these numbers are more than enough to keep the industry strong all things considered. Unlike the PS2 days, we have multiple platforms with well over a 100 million active users each. This is without counting mobile phones.
There has never been a better time to make quality games, because there are more players across multiple popular platforms ready to spend a lot more than the average gamer of the old days. Naturally, this leads to a greater software output and sales but also a larger number of flops, because countless smaller companies will attempt to get a piece of the pie.
The most dominant home console of all time (PS2) had a tiny number of 10 million+ sellers. Competitors at that time couldn't dream of reaching 10 million in software. Fast forward and now the 10 million milestone is so regularly reached, with several games exceeding 30 million, and a few 70+ million. Even Devil May Cry and NieR Automata are 10 million sellers.
