It looks fine. I might check it out once, but there aren't a lot of games I'm really interested in playing and it doesn't do a ton of new stuff unless it's Xbox related, which as we all know, they don't have a good selection of games. I'd probably at least play Shadow of the Tomb Raider so I don't have to pay much for it, maybe see how the Banjo-Kazooie HD games look like on a PC, see if there's any sort of better performance there (I don't exactly know how the service works)...Maybe Halo 5 and the Master Chief Collection for the heck of it? I could probably at the very least get something out of it for a month.
If there is anything I could say positively about it, it does seem like a vastly better value than Playstation Plus. Makes that look super shitty in comparison especially now that they offer even less games a month.
