I Prefer Jungle Lord over Black Knight. Parts are pretty easy to get, plastics are harder to find, but scans are out there to make your own. Overall pretty good game for the money.
I really like mine,of course my collection isn't all that strong.I have a galaxy and just acquired lights camera action and jungle lord is the one that gets played almost daily.It is pretty challenging and i'd say it has replay value as once i start playing i'm stuck playing for 5-10 games or more.
