Been playing
Saint's Row: The Third. Heard some good things about it and it was on sale for something like $12.
Good fun so far. For those who don't know, it's basically a cartoonish version (though the graphics are roughly on par with) GTA IV. All the parts of GTA IV that stopped you from going insane, but added to the game's challenge and realism, are gone here. Insane outfits, tasteless weapons, action-movie mini-games. Little "activities" strewn around the map where you do things like shoot people in mascot costumes on a reality show or see how much damage you can cause in a certain amount of time...with a tank. And you can purchase ridiculous upgrades that let you run longer, take less bullet damage (and eventually none, actually), etc.
Put it this way: one of the first missions has you skydiving out of a plane and shooting other skydivers as you fall.
It won't blow you away, but the general insanity is pretty fun, and it's willing to do just about anything to be entertaining. And I do find the little changes of pace effective in keeping things interesting. There's never too much time on any mission where you
just run around shooting people. They mix it up with car chases, by having you protect others from afar with sniper rifles, or with a rocket launcher from inside a helicopter. Or they have you pick someone up, evade others, and then drop them off. It feels less realistic and the city less "alive" than Liberty City did, but GTA V would do really, really well, if it's not too far along, to take a page from their book when it comes to things like side missions.
I've only played about 18 hours over the two weeks since I bought it, and I'm pretty sure I'm already down to the last handful of missions, so I'm running around doing random stuff for now before finishing it up. Solid game.
