This is the first product from this company as far as I can tell so I'll be constructive: hire an editor. Yes, a real one. And then decide which edition you're publishing for. If it's 3E then having ogres armed with Huge longspears or whatever is fine. If it's 3.5E, you might want to try again. Also, the space for a vrock is 10' not 10' x 5'. Should I go on? I will. Damage that differs depending on the size of the opponent went out in 2E. So which edition is this adventure for again? Oh, and "it's" is the contracted form of "it is". The possessive form of "it" is "its" without the apostrophe. I accept that 90% of messageboard users haven't grasped this but any sort of professional publication should be able to get this right.
The adventure itself is nothing spectacular. Several encounters with an attempt to use the tactical format in a manner similar to WotC. Really, this products needs to be looked at with a fresh set of eyes and then reissued. It's not good and certainly not a good first product.
