Frank West was the protagonist of Dead Rising, the brilliant - though flawed - zombie sandbox beat em up. For the much improved upon sequel, Chuck Greene took over the top spot. Some fans were outraged that Frank (who had become the subject of more than a few Internet memes) was being replaced, and I just never understood that. Not only wad DR2 a better game but Chuck was a perfectly acceptable character.
The two met in DR2: Case West (which I haven't played yet) and now, in true Capcom fashion, the updated second version of DR2 will take place in an alternate universe where Frank is once again in Chuck's spot (Dead Rising 2: Off the Record). Is this necessary? What's the huge appeal of Frank?
