I'm hard at work on my set of house rules. It looks like they are going to be under 8 pages long, but it is taking a bit more time that I expected as certain aspects require a more thought and explanation than I had planed for. The biggest obstacle so far has been creating a set of simple critical hit rules that won't slow down gameplay. Currently I'm leaning towards a basic and an advanced system that you can choose from. The basic system does not require a lot of record keeping, but doesn't give any detail to the injuries sustained. This has more of a wargame feel. The more advanced system gives detailed descriptions of the injuries, and creates the possibility for permanent effects (loss of a ability point, blindness, limited movement etc). However this requires more record keeping, and slows down combat. This system feels a lot more like Rolemaster or WFRP. I'm going to have to playtest these to see what works best. Hopefully I'll have a rough draft of the rules finished tomorrow or Monday, and I'll post a link to them when that happens.
Tentatively I am calling the rules "Delvers of the Deep" or DotD.
