Completely disagree. In fact I hate Rogue Legacy and all 'rogue types' because they think randomness = interesting.
Rogue-like games plague the Steam store [1], though there will always be games like Legacy that rise to the top of their category. You could say Candy Crush is an objectively successful game too, but I see it as a micro transaction laden piece of trash.

The claims you made beyond that are invalid
Surely... Though, you can't point to community and critical acclaim like you could with Rogue Legacy, which is why they were linked and why the other poster was suggesting you back your statements with evidence. It's less so for people to like you or your comments and more so for people to gauge the veracity of your statements...
