I'm at 5% when I'm writing this. I liked the previous Frogware Holmes themed games that's why I bought this game. So farI'm getting familiar with the controls what's a bit more complicated than I like it but can save myself from battles by turning that feature off completey. (if I want to play a shooter game then I'll play a good one) In the first quest I have faced the 'your decisions decide how the story unfolds' feature. However I was still limited what bothered me a bit. I will come back later to revisit. So my verdict for now is buy it!
(I've just started playing the game) Some confusing elements so far but overall the game is the best S.H. IMO so far. (I'm a big fan so I have all the SH games) (Currently I'm stuck with the armwrestling quest XD ) After I finish the game I will update my review!
