In short, the scenery and immersion is achieved, the city and superb! It's relatively small size compared to GTA giant but very respectable and very pleasant becuase background one can really visit it from top and walk is a pleasure!
The missions and the scenario is very successful, even if it could have been much better with more emphasis on the cop side / thug and digging more ... But we can not ask too much ... The lifetime of the missions main is very respectable, especially as there side missions that are fun to do. In my memory, I finished the game in full (main and secondary missions and all the quests) in thirty hours.
Gameplay side, the bare hand combat system is excellent !! It far surpasses that of GTA by far! There combos keys learn little by little and we win the combat experience and therefore new moves by going to the dojo to learn from a master new combos that will apply in combat!
Driving cars on it is very arcade but very easy to handle and is fun to drive different cars. Driving is on the left because Hong Kong is a former British colony, it is exotic and it's good to change a little bit :)
Big black spot on the conduct of vehicle in reverse, the camera tends to buger and is badly configured. Fortunately, we do not much back on, but it's really lousy and boring.
Otherwise, the other negative side is clothing: there are a number of clothes to buy a few shops to customize our character, but I think there could be some more! That's what I love in the GTA-like specifically: customize my character and change his clothes regularly, in short, to do with the image I want and in this sense, I find it important to have a choice. there is a lot of choice eh, but still + would have been really excellent!
Finally, this game is a great GTA-like, I loved the canvas background Hong-Kong Triad and the universe, I have indeed taken a lot of fun playing it because it is very immersive and finely realized . Even ancillary activities are fun: mahjong example, popular game in China. Radios in the car are excellent and well chosen music level (we discover some Asian titles very nice!) The unarmed combat system is excellent, shootings also are nice, short, the game is really good entertainment.
The 30 hours spent above are good memories, vividly on! Anyway, I highly recommend this game from Square Enix is for me one of the best GTA like with Saints Row 3 (obviously without mention GTA are THE ultimate reference).
