Thanks for posting this!
Lost World games are great fun. You can start a whole minis collection and a campaign for the cost of maybe half a dozen adventurer minis. After that the only expenses are thunder lizards, giant bugs and snakes, and some terrain. You are talking maybe 10 bucks for all the gaming you could ever want.
However, no need to stop there. Add in your Zulus as local native warriors, European soldiers and sailors, the temple of some forgotten god of darkness, a crashed tripod or two, there's no limit!
