Nope, it gets easier. However, when i was reading about dead rising everyone was having trouble on the final boss (Brock), really don't know why as he's easy.
Tbh, if you die after about lvl 30 playing the case files, then you suck and if you die on lvl 50 then play something else

I had so many spare items slots on lvl 50 (stock, whatever you call it) that i had 5 adam the clown chainsdaws with all the books (8 slots) a shotgun (don't really need it, but i'll carry it for the heck of it) and a few ojs

. It's overkill basically, but at least i never had to worry about weapons after i beat adam
And mcdaniel, i was catching up with you on gamerscore a few days ago, but not now. You're caning these new games
