Seriously, no one else wanted to talk about this game yet? I searched and saw nothing (both proper and improper spelling).
Anyway, this game is awesome. It's nice to see games that forget realism to be over-the-top amusement. It's hard to even decide what features to even talk about as there is something new to do around every corner in this game. Hell I thought the first game was good, this one expands upon that several times. This post will come off as an ad because I am enjoying this game enough that I feel the need to cheerleader it.
Lets see, off the top of my head, things to do in Saints Row 2:
use shock paddles to kill someone, then revive them, repeat.
go streaking/flashing
use a septic truck to spray shit all over people/property
"races" that involve you riding a 4-wheeler around while on fire, setting other things on fire for bonus time.
pretend to be a cop for filming of "reality" television
operate cars, trucks, motorcycles, boats, jetskis, fighter planes, biplanes, triplanes, small jets, helicopters
customize cars, trucks, motorcycles with mostly pretty impressive options (some vehicles don't have as many options however, but most have tons)
customize your character pretty impressively as well. First sandbox genre game I can think of where you can play female, male, or to some degree, a mix of both.
almost anything you do while driving and fighting has stunts you earn rewards for (think crazy taxi for driving)
take hostages, human shields, throw people through windows / off buildings, hold up stores, and plenty of other assorted illegalities.
pretty decent multi player modes (the brawl/deathmatch stuff is kinda boring in my opinion though, probably because I suck. Strong Arm is fun though.)
Co-Op play for the entire game! You can play from mission one to credits roll with a friend, and it is fun as hell. You can also drop in / out at any time, but for achievement's sake it seems to be currently smarter to have a separate play through/save for co-op (although they may be patching this).
So yeah, anyone else playing this? If you enjoy sandbox games at all, you should really give this one (and the original for that matter) a shot. Hell, is this the first sandbox game to have a direct sequel with the same characters?
