Sadly, that's now just a wishlist - The BBRC and Tom writing the rules are distant memories now.
We'll have to look to Jervis to get things moving again on the rules.
I like the majority of those suggestions, except maybe 6 - Stunties would actually be a serious threat; maybe it's to make them more Dwarf-proof.
I think some of the mutations actually need a touch of pimping - e.g. Tentacles aren't all that good (on lower Strength, but that's just me trying to make random mutations work!). I'd like bigger bonuses on some, with a minor drawback. I remember the Carapace mutation - +2 AV, -1 MA, and Obese. I can't remember the exact bonuses, but it could easily affect all the stat lines - +1 S and AV, -1 AG and MA. +1 S might be too good, but you get the idea.
Gerard, where did he post this, TFF? Linkie, please!
