I'm thinking something more like "Dead Rising 2 cannot suck." I am (or at least was... until I pried myself off of it about a week ago) completely obsessed with the first game. When the setting for the sequel was announced, I worried a little... what can you do with a hotel/casino? But now I'm not worried at all. The shopping mall was stretched quite a bit (two hardware stores (whose unique items sort of bled all over the North Plaza, being that it was under construction), antique shop, gun store, blade store... for some reason there were traffic cones, paintings and other stuff in the movie theaters and a katana on the awning outside of a cafe).
Now, about that guy's complaints.
-Frank sure isn't weak for me anymore. At level 50 most of his moves can kill zombies with one hit during the day. Hammer Throwing one zombie can take out several.
-"Closed-in" environment... well yeah... you're trapped in a mall...
-Repetitive missions: Valid point
-Stupid AI: very valid point
-The convicts: Easier to kill than it seems. Even without the Real Mega Buster (which is easier to unlock than it sounds--just mundane). They do spawn every midnight except for the last one though, somehow. Blah.
-Otis: I don't have a problem with the repetitive calls so much as how helpless you become when answering them--and getting attacked ends the call and Otis calls back to scold you for hanging up and restart his speech. Ironically, Otis is renowned as being the most talkative character in the game, yet has no actual lines in cutscenes, ever. The closest thing he has to voice acting is in Infinity Mode, and even then I don't think he says any real words.
-Frank can's unarm himself: Yes he can. Up on the D-Pad. Why would you be carrying so many books that you can't carry anything else? Most of them augment other items.
Overall I'd call Dead Rising the easiest Capcom game I've ever played... excluding Phoenix Wright (though some situations there don't even make sense).
