CRAZY FUN
Saint's Row 2 has a ton of stuff to do. There are the main missions which are based on gaining back the hoods that rival gangs have taken over. These missions vary in that some are driving, some are gunning and some are both. Besides the main missions there are plenty of side missions that are under the categories of Activities and Diversions. The Activities range from Insurance Fraud, Gathering up Hookers, Destroying the city to Bringing down property values by spraying crap from a sewage truck everywhere. There are also the standard "hit man" and "chop shop" missions that were in the first game. Completing these missions unlocks bonuses like cars, weapons and new abilities. They also earn you money which you can use to buy tons of clothing, weapons, ammo, and upgrades. Plus you earn respect which is needed to unlock the main missions. Diversions are fun mini games that are optional. Some diversions include base jumping, putting out fires, towing cars, and working as an EMT. These are just a few of many things to do in Stillwater. Like the first Saint's Row there are all kinds of things you can buy.
There are many vehicles which can be upgraded and customized buy driving into one of many garages. Once in your garage they are yours whenever you want them. You also have a huge selection of clothes, accessories and character customization. Where do you keep all this stuff? In you crib, where else? Spread throughout the city are places you can buy and upgrade. Here you can pick up the money you collect from the hoods you have won back and from the businesses you have bought into. You also have access to you clothes and weapons. This time around you have the option to play co-op with your friends. If that's not your thing you can try the multiplayer. Even though they removed a couple of the multiplay game modes you will still have a ton of fun.
Everyone compares SR2 with GTA4 and at its core they are similar. The difference comes in that GTA4 went for realism and SR2 went for just plain fun. In SR2 you have the option to spend all that money you have collected. Whether it is cars, clothes, homes, or weapons it gives you more of a feeling of satisfaction. If you liked GTA4 I can't see how you wouldn't love SR2.
