I like ER alot as well ,but after playing Ds3 i kinda enjoyed it more .
Sure ER is huge and fun as well ,but as example overall Boss Quality is much better in Ds3 .
I mean let‘s see what the upcoming DLC does to my opinion.
In ER there are imo to many recycled bosses ,as example the Grave Watchdogs .
ER is great because you can literally go anywhere from the start and if you hit an roadblock ,just come back later stronger or better .
Ds3 is much more of a challange sometimes ,because story is much more straight forward ,you can‘t go almost everywhere from the start.
You can‘t use spirit ashes or can‘t summon npc‘s if you don‘t have certain quests unlocked .
And after Ds3 ,i miss that they don‘t put Covenants in ER would be so cool for invasions .
