I looked it up for myself just now and here's the actual data: between hard-copy releases and digital downloads combined, there have, as of this date, been...
You can't just look at the official search results that come up on the official stores because those include a metric done of duplicates due to the fact that those list bundles as separate games. Once you focus on actual unique titles, these are the numbers.
Anyway, the numbers are close! However, the PS4 already has slightly more games at the end of the day, and, unlike the 360, still isn't done.
However, this said, looking up the total combined number of games that were ever released for PS1, PS2, and PS3, it also looks like your original claim that the early version of the PS3 that had backward compatibility was the system capable of playing the most total games may is probably still factually correct as of yet. The PS4 probably won't catch up to the combined total of all those games.
Also, counting both Virtual Console (659) and WiiWare (463) releases for the Wii, it looks like that system also had more total games than the PS4 so far (a little over 2,600 grand total), although the PS4 may very well yet catch up.
Those are the only two that have more total games though.
Well that 360 number doesn't include the 3398+ small indie games that where available on the 360 at one point or another. The total number of games available on the 360 during its entire life span was over 5000+.Last edited by Chris Hu - on 15 August 2019
