You can now fine-tune your aiming by tapping down on the D-pad and then holding in the L button. But even so, its the type of feature you'll forget it there, because its unessential. Many missions require you to wonder into a crowded area and pick off specific targets while everyone around you opens fire, but you can tap R to lock on to a target.
You often have to be quick, because you'll either struggle with aiming or you'll use all your ammo wiping everything out. As a value proposition, nothing comes close to this on the PSP. It is a gigantic game and will likely take you 40-50 hours to complete and even then, there are 33 other "games" inside it, that could take 5-10 more hours.
There's the firefighter, vigilante, and taxi missions; there's also package collecting, delivery missions, races, and shoot-outs; and on top of all that, there's this whole multiplayer thing. The 7 modes borrow ideas from the tried and true multiplayer school of design, but the difference is in the way they use the whole environment and cause the player to learn the map.
If however, your not really a multiplayer person, then there a few modes that will be fine for just you. The deathmatch and marked-for-death style modes do 2 players, but the full effect comes from 6. There's a capture the flag mode which has you stealing limos, and finally a "wedding list", which is a free-for-all scramble to take cars and drive them to designated shipping crates.
As you can probably tell, LCS has plenty to distract you from the main story, but as we've come to expect from Rockstar, that core experience is extremely well written (although its subtly but spectaculary and hilariously puerile, especially when it comes to character names) and well paced. It's slow to start but things start to pick up around the 5th hour when it reveals to be a complex story and a more political one than we're used to.
The ways of the different criminal organizations and the way they want the city run, really make for an interesting tale, especially around the 10th hour when you start to put yourself into the mayoral race. Missions are shorter than on the PS2, and arent the lengthy stuff we saw in San Andreas. It's usually no more than 1 step, such as kill this guy, and there are only a few 2 or 3 steps, which are like follow this guy and blow this up. The result is a more user friendly game that is good for killing 10-15 minutes.
Initially, Toni Cipriani isnt as good a character as CJ from SA, but as the story unfolds, you learn to appreciate his more cliched Mafia stuff and some of the way he handles characters are straight out of The Sopranos; but as you explore his loyalties and watch the relationship with his mother unfold in a bizarre series of events, you learn to sympathize with him. In the end though, he is just like CJ, because you develop a bond with him.
The load times in LCS are quite impressive. The city loads quickly and never stops to load, and the only time you're out of the action is in cutscenes, and even they are transitioned quickly. Plenty of music is pulled from the disc, and the whole game has a lot of speech. But all this comes at a considerable cost. Playing non-stop, and at full brightness, with Wi-Fi off, we were only able to get 2 hours and 30 minutes of playtime. But with Wi-Fi on, we were not even able to get 2 hours.
This game should be commended as should Rockstar, when other game makers are pushing ports and other stuff of their mega franchises, this game is worthy of being called a full-on sequel and is comparable to GTA3.
