Games, ideally first-party ones. I think they need to recognise that as much as they're comfortably ahead of Xbox this generation, there's been a growing amount of negative sentiment building towards PlayStation and it doesn't take much to tip fans and gamers in general over the edge. A highly-anticipated game gets cancelled while games nobody cares about get released to die, a focus on live-services titles instead of the single-player narrative experiences PS is known for, lack of variety, and lack of support for PSVR2 plus its high cost of entry.
They're not stupid, they will surely recognise that many of these will factor in to whether people feel willing to pay £800 for their latest device, but they need to turn it around. Astro Bot has saved them from an awful lot of embarassment because otherwise the current conversation would purely be about Concord and the Pro pricing, but they need more wins like that and fewer games stuck in 8 year development hell. We got three original games from Naughty Dog during the PS3 era including one entirely new IP, it's baffling and disappointing that we've still had nothing genuinely new announced from them this far into the current generation. There are still games shown during the original PS5 announcement that aren't out yet; that Capcom sci-fi one pops back into my head every now and again, even if the name doesn't.
