With the gravity of this announcement and what it means for the industry yes I'd say 20 pages in nearly 24 hours seems a bit low. This is a big deal but for whatever reason the announcement seems to be getting very little traction both here and elsewhere. I figured this would dominate the news coverage and discussion in enthusiast forums but it decidedly has not done that.
I think you're falling into the same trap a lot of people are in this thread when you're overestimating the importance (and quality) offered here: the game selection is deeply unexciting. A lot of people seem to be imagining that it will be like EA Access, or gaming's answer to Netflix, but everything Microsoft have actually put out suggests it will be neither.
I feels like a lot of people are neglecting what is obviously going to be the main problem with this subscription: the game selection. To advertise this new programme they've stuck out an image with Halo 5, Saints Row IV, Mad Max, NBA 2K16, and Lego Batman in the foreground.
I'll get excited when Microsoft (or someone else) offers a subscription that could replace most of my retail buying. Until then, I couldn't care less. I'd buy EA Access before I bought this because it offers me free trials to new games and their entire lineup, free, usually within a year of release. This offers a game selection so uninteresting, going off their advertising, that I don't really know who it attracts. It's a reasonably cheap way of accessing a large number of old games, many of which weren't particularly well received... it might be able to find a market amongst gamers who spend less on the hobby, but I can't help but feel they tend to be the gamers who obsessively play a small number of games like FIFA, Call of Duty, Minecraft, etc.
