PlayStation Classic Won’t Add Games Post-Launch
"More news about
PlayStation Classic are coming day after day, and
IGN US has managed to obtain some of them contacting Sony directly via email – with the topic being the selection of the games, the possibility that more titles could be added post launch and trophies.
"The news are not as great as one could’ve hoped, but to be honest they’re quite predictable. As with Nintendo’s NES and SNES Mini, PlayStation Classic won’t allow to add more games after the release and won’t be connected to the net.
"There are no plans to bring new content to PlayStation Classic post-launch," a PlayStation spokesperson said. And the same goes with the trophies, which are not going to be added on top of the existing classic titles."
