like what cleglaw has said, sacred might fit your bill. it's hack n' slash like diablo, not much in the way of storyline (again like diablo), and there's plenty of items to collect (need i say it one more time? just like diablo. lol)
it even has a ladder system, again just like...well, you get my point. <img src="/ubbthreads/images/graemlins/silly.gif" alt="" />
