I mean really playing them. Like putting 100s and 100s of hours into all of them even a thousand hours. And learning all the mechanics. Playing all the different characters, trying the shit ton of builds with all the chracters, plus all the possible gear combos with them all. And then theres the millions of different weapons and gear. Thats just some of what the games have to offer. And its leagues more then what destiny has. If you really really played borderlands. You would in no right mind pick destiny. But hey to each his own.
