Skipping around in here, people liking BB more sure seem to be aggressive about it. Poll getting to y'all.
Considering that BOTW is far more accessible and has sold 4 times as many copies, I think it is highly likely that many more people have played BOTW than Bloodborne.
Considering that, it is very impressive that Bloodborne is so close in the poll and likely that Bloodborne is winning among the people who have actually played them both.....but don't let it get to you.
