Other than that, and the remastered audio and visuals, it’s basically the same
In case you forgot, Sony is remastering PaRappa the Rapper for the PS4, and it’s out soon-ish! They just confirmed an April 20 release date for the project, which will be priced at 1,800 yen (roughly $20), and will come with six PSN avatars for “early purchases.”
New features include trophy support, 4K/1080p visuals, and a remastered uncompressed CD quality OST. The only gameplay changes are a metronome-like mechanic for DualShock 4 controllers, and enlarged icons.
Although I think a fully remastered collection of all the PaRappa and UmJammer games would have been preferable, the first entry is still an easy, obvious choice as they don’t have to change much — it’s still a classic that I replay every year.
