Probably not, but I'd be tempted if the cost was a bit lower than $60 per year and if there were more interesting indie/early-gen (discount) titles. Although, I think that prospect might be a bit impossible if the service didn't implement the ability to vote on a wider range of options. Personally, I'm a big RPG/Open-World/FPS nut on consoles.
I'm not aware of how well the Xbox Live handles its service at the moment, but I see PS Plus frequently gives out walking simulator/adventure games that I really don't feel like investing my time into. Some of them are really good (love TWD games from Telltale), but I can't see them making a service that appeals to everyone every single month. I can say that I like the Humble Monthly more often than I do the PS Plus free games, but I did appreciate getting MGSV:GZ and TPP, that was pretty sick.
