Summary:

- The article discusses 5 Sony intellectual properties (IPs) that the company seems to have forgotten about or neglected over the years. These include franchises like Syphon Filter, Ape Escape, Twisted Metal, Resistance, and MediEvil.

- It suggests that Sony has been focused on a few of its major blockbuster franchises like God of War, Uncharted, and Spider-Man, while allowing these other potentially valuable IPs to languish without new entries for long periods of time.

- The article speculates that reviving some of these forgotten franchises could be a way for Sony to expand its game library and offer more variety to PlayStation players, rather than relying so heavily on its most popular series.
