I was looking at the Chaotic Caves just on Friday. I decided not to review it right now, because it appeared to be SUCH a knock off of B2.
You're inconsistent, mate. JD Neal's Hill Giant module that "channels the spirit of" G1 "without plagiarising it" gets two thumbs up from you. The same bloke wrote a humanoid-tribes module that channels the spirit of B2 without plagiarising it and you call it a knockoff.
It's got exactly as much to do with B2 as SG1 has to do with G1. Far as I can tell, the only difference is that you don't like humanoids. I like humanoids; from my perspective, humanoids lead to interesting positional battles where combined arms tactics matter, whereas most weird gonzo science-fictiony monsters are either boring hackfests or else they boil down to "Can you guess how to kill this one before it eats the whole party?" Which is arbitrary as well as boring.
