Grand Theft Auto: Chinatown Wars I got this game from Amazon for a great while ago. It was one of these apps that remained an iOS exclusive (on the smartphone side of things) for a long time, until some day, the Android version was spawned.
I immediately caught it with my Amazon coins and every while and then, I slowly made a little more progress. The end result is around 89% with all the main story complete along with the unique jumps. Unlike other GTAs, this one tends to break the norm of what we've seen of GTA up until that point. For example, one of your missions is the typical GTA racing mission, but played out radically different. Rather than race and be 1st place, you help another guy race and be 1st place through cheating him.
The top-down-like (not fully top-down!) gameplay makes for some interesting changes: no flying vehicles for starters. Also, nearly all of the vehicles have twitchy controls which make them hard to stabilize. Your main character can run for distances without tiring and can hold a variety of weapons, although GTA IV's limit on ammunition is retained. There are your security cameras which act as the hidden packages (and must be destroyed with a thrown weapon like a grenade or Molotov), rampages, and unique jumps (which are spotted by a distinct billboard that must be crashed through for the jump to count). Driving over people and police chases are all there, except the driving over people part is easier as the speed decrease from doing so is severely diminished, and the police system allows for a gradual escape from the maximum heat level to the lowest while on-chase and without relying on Pay n' Sprays.
The setting is based on GTA IV's Liberty City, but with an entire mainland island cut off and the ground totally flattened for the most part. You play as Huang, a Triad who is visiting Liberty City to avenge his father's death and delivers an artifact sword of utmost importance, but ends up ambushed and almost-killed, and with the sword stolen. The game revolves about him slowly learning everything around him and finding his father's murderer.
I think that should do it justice.
