At the moment, I'm binging in Monster hunter World, 142 hours in counting, but I think if it weren't for this game's entry, I'd have to say flatly that it's Blade Symphony. It was one of the first few games I purchased on Steam when I did my first gaming set-up, and I absolutely adored that game. It was worth my while, and I spent over 500 hours playing it altogether, for the years I have had it. I'm waiting for its f2p release so I can bully some new people in it, but it's just been my favorite. World is good for its co-op, whereas I suppose Blade Symphony would be my go-to PvP game. It's just THAT good.
