PSOne Classics for PS4 with trophy and OS support might be revealed at PSX
Back In 2015, Sony sent out a survey listing all of the PS4 firmware features that gamers may want. In addition to the likes of folders, the questionnaire also included mention of PSOne and PS2 Classics. The latter format launched late last year at PSX 2015, but we're still waiting on the former to accompany it. According to various trademarks, we may not have to wait much longer though. The latest trademark for Lifeforce Tenka happened on October 28th, 2016. Just in time for this year’s PSX.
The majority of fans love the idea of PSOne Classics on the PS4, but while some feel that these should feature cross-buy with the PS3 versions they’ve already bought, others think that they need to be fully integrated into the new-gen system's operating system. Trophies may not be everyone's cup of tea, but they do offer incentive to revisit decades old experiences, and when coupled with the ability to livestream and share screenshots on social media, classic games are certainly infused with new energy. But that all requires time and effort, which the developers will want to charge for.
In a survey, 63% of participants voted “I’m willing to pay for Trophies and full OS integration” while 37% voted “Ditch all of the extra features and give me cross-buy”.
