I think it's a little weird to single out skill trees as an issue here (because it's more widespread than just Playstation), but the criticism of recent Playstation games being of a similar flavor is otherwise valid in my opinion. They definitely have the 3rd person, AAA formula down to an artform, and it's doing great things for their brand. So no, I don't think they need to change their strategy at the moment. As a fan however, I will admit that the experiences these titles offer—while still fun—can get a little Deja vu-ish at times. To be honest, they are mostly being carried by superior storytelling, and don't really offer anything that innovative in terms of gameplay imo (although, it's probably because I'm kind of shitty at games, and tend to take a stealth approach in everything I play). So as someone who mostly games on Playstation, would I like to see them explore other genres? Sure! Of course. Why not? It'd be interesting to see what Sony's studios can do creatively with a big budget platformer, or first person shooter, or tactical RPG, for example. Do I think they'll go down this path? I'm not so sure. There's a lot of risk in it for Sony. Why mess with something that's working great for their bottom line? They have found their niche, and have built a fanbase upon it. While I'm definitely interested in certain games that Xbox and Nintendo are putting out, there's not this great sense of FOMO because Sony doesn't have similar titles. Just like I don't sense a huge deal of FOMO coming from Xbox or Nintendo gamers towards what Sony has in its lineup. We all have different motivations behind our decisions to buy these plastic boxes. I didn't buy a Playstation expecting to play games like Halo and Mario Kart. I bought one because I was specifically interested in the narrative driven, big-budget games that Sony is known for. If and when their games are no longer fun for me to play, or I find the storytelling growing stale, I'll leave Playstation and look for something new. If that begins to happen en masse within the Playstation fanbase, then Sony will have a huge problem, and change will become imperative. While I don't expect Sony to screw up too badly any time soon, I certainly don't think they are incapable of it. They seem to be wanting to fuck around in the TV and film space recently, and if this becomes a new obsession for them, it could distract them from focusing on making high quality games. I don't think it's likely that this becomes an issue, but I'd keep an eye out for it nonetheless.
