I totally get what you mean here. I stumbled onto EZG a while back when I was hunting for some extra currency in a smaller game that barely has any reliable sellers. I remember thinking the same thing, like most sites only hype the big ARPG titles and forget everything else. EZG actually surprised me because they had stock for the exact game I needed, and the delivery was smooth without any weird issues. Their customer service really did reply fast when I asked something, so that part in your post hit home for me.
If anyone here is wondering whether EZG is legit or worth trying, my two cents would be yes. Just stick to their recommended payment methods, check the coupon, and you should be good. The experience feels way safer than a lot of random marketplace sellers I used before.
Also, since you mentioned needing trustworthy platforms, I once had the same stress when doing school stuff too, and I remember ending up using a trusted Research Paper Help Canada which helped me stay sane during crunch time. Funny how both school and gaming need reliable places you can fall back on.
