I never used it, far as I know no one watches me play and I don't have time to make sure others can since I rather just get in and start gaming without distraction.
I think the only one I ever pre-ordered as the Dissida PSP edition, which I paid in full. Otherwise I wait for after releases and make sure everything is good, unless its a very special edition that I want which is rare.
I don't think so, out of the big three it seems like Xbox struggles to keep up with Sony and Nintendo, so I can't see another coming in and matching the others in what they have going on.
Far from it, plus they release over a dozen games on their eshop each week. Seriously, check it out the eshop is over flowing with games right now and they got more coming.
I never understand why they release a console when they have the PC market.
Anyways, Nintendo has a big lead with the Switch, but I feel the PS5 will catch up and surpass all.
I think the series is pretty big actually, they just took their time with it due to slow source material. Which they don't seem to pull much from the web comic version of the series.
