The cops are a pain. I was walking by on the police station and some guy started talking a ton of shit to me and daring me to fight. I got in his face and the cop standing outside folded his arms and told us he was the law and we better back down. I decided to punch the guy. The cop killed me before i even got my gun out.
Maybe the version is lacking some features. Online would open up a whole new world of possibilities. You can do a ton. Might be worth buying for that.
This is how a guy described it to me on another forum:
The number of options is huge. I believe there are 500 online missions at launch, and they're constantly adding new ones and taking away missions that people have voted negatively on. They range from competitive deathmatches and races, to co-op story missions (the online has a loose story featuring characters from the single player with cut-scenes), to parachuting. All are full of insane variation; start a race and it might be stunt biking through an airport, or racing rocket-launcher equipped sports cars through the desert. You could end up stealing money from a bunch of drug dealers with your friends, or trying to kill a bunch of racing motorcyclists in jet fighters. You can play golf, tennis and the other side activities too.
There's also freeroam which acts as a hub to start missions where you can buy houses and cars as you rank up and get more money. As you rank up you'll also get access to increasingly more powerful free-roam options, from putting a bounty on a players head to ordering an airstrike. Rockstar are also in the near future adding a map editor so that players can create their own races and deathmatches which will be rotated at random too, so content will be essentially limitless.
