I thought of something stupid but here goes anyway. would it work if monsters
level (or easiness in general like bunnies) wouldnt be killable if you were
high lvl enough, like You feel that is too easy for you to rape. or maybe just
lower the exp from it, like highbies would have to kill something bigger to
get something of the killing. If youre a highbie whos (or atleast should have)
seen everything possible, killing small monsters doesnt feel too fun. This
would leave newbies with lotsa smaller monsters to kill, whenever they run
into smurville, it wouldnt have been ran over by some lvl 80+ clueless fuck.
hmm yea, this idea sucks, shoulda posted it in bs.

There would loads of problems with system like that. In many areas there
are small mobs which hold important keys, items etc and I dont want
to reveal all my secrets to some newbie just because I cant kill
that particular mob. Im sure theres lots of same kind of problems
in system you suggested.
