Not surprised that Hotline Miami 2 got 5/10. I can't say it's a terrible game, but it was not particularly good, either.
Edge use the full scale, and 5/10 is decidedly mediocre. I bought HM2 thinking, "Yeah! Gonna get some new levels for Hotline Miami 1!" No. Just, no. Instead we got cheap ass enemy AI, spray and pray gunplay, and atrocious level design. This is, of course, peppered with some amazing moments that balances out, but I can't say I enjoyed my time with the game. Really, what an unfortunate sequel. Mediocre indeed.
At any rate, there's some goodness for me on the horizon, should Edge's scores be gospel (or, at least, an accurate representation of how much I'll enjoy a game): my copy of Bloodborne is on its way, plus I'll be grabbing Axiom Verge and Ori and the Blind Forest soon enough.
That said, I'm curious as to why Titan Souls got a 5. The game looked quite interesting!
