Yes, its filled with COOL STUFF, which is so incredibly unlikely to be the case in any plausible world! I mean, lets imagine an RPG set in a reasonable facsimile of the real world. Maybe its a crime drama, and its set in Renton, Washington (the home town of WotC, I happen to leave down the street from their HQ). What, realistically, will the PCs encounter? It will be drug dealers (not very exciting ones at that), a lady with no legs who yells at you whenever you pass her by at Fred Meyer, a bunch of very indifferent cops, an assortment of homeless people and druggies, and many ordinary citizens of various ilks.
I mean, maybe generously there are a few Chinese Spies lurking in town? I strongly doubt it... Its an ordinary place, like every other place in this country, basically. That's a place that is not specially built to cater to PCs in an RPG. That's what I expect every ordinary sort of place, and even the less ordinary places for the most part, to look like EVERYWHERE. If you want it to be plausible, to really tick the box of "this could be real" then that's what you need.
There are ZERO RPG settings in the entire history of RPGs from day one which look ANYTHING like this. End of argument!
Well, that's your opinion, and you are entirely welcome to it.
