Sounds like a recipe for player frustration. I know people who couldn't handle 243 Riddler trophies in Arkham Knight; imagine that being snowballed into 500x.
Oh also get to explore Miagani Island,Bleak Island,Founders Island, North and South Gotham, Arkham Asylum, Arkham City, Wayne Manor, and the Batcave in free roam
I know there will be a lot of Riddler trophies, but think how rewording will be to finish it, and people will have a Way more things to do in the game
They don’t make you finish it you do it on your own, and I think that it’s better to be annoyed and trying to find more trophies but overall it’s better than just not playing the game.
I understand you guys may be younger than me, but people have other things in life outside of Batman and video games. Just think of having to track down roughly 20-50 Riddler Trophies an hour and trying to fit that around a tight schedule, such as work, cooking, bills, social arrangements, etc. Trust me, that many Riddler Trophies will get boring quickly.
