Everything you'd want in a GTA game on the Ds.
The gameplay is different from traditional GTA games obvious reason being because its on the DS. But for some reason its more fun. You get to hot wire cars, make Molotov cocktails, and best of all sell drugs. Those are the most notable differences, everything else is what makes it a GTA game. There are plenty of missions even downloadable ones in the rockstar social club website. Driving around has never been so fun with a huge city on the go! Plus doing things to get you to 100% such as Unique Insane Stunts.
The Graphics seem to be 2.5D since some things are 3D but from your view almost everything looks 2D. Like most DS games there are jaggies but this game makes it look good. Weapons and other items look pretty realistic. And the cars look pretty good too. People though look sort of bad but its because they are tiny.
Everything Sounds like it should. Cars sound like cars, Guns sound like Guns, People sound like people, and Punches sound like the Cartoon Punches we love. Some things sound so authentic its crazy like when your pouring gas into a bottle and hot wiring a car.
The game as mentioned before will last you a very long time, therefore its definitely worth purchasing. And If you finish the game quick there are extra missions online and also online multiplayer. The only thing the game doesn't deliver in is in story-telling. It's too original and you get the Been there Done that taste when your playing. The Characters are also unlikable because they are all A-holes to each other. Some may think that's cool but it gets annoying having to deal with it EVERY cutscene.
So In Conclusion....Buy It. You will love it. Its an experience that not many people who only own Nintendo systems can experience and probably won't experience again. You get what you pay for this game, its truly an experience that must be experienced.
