these home rules, mind if I ask about them? Are they geared towards a specific feature or theme? realism, fun, access?
I have yet to set them to paper since I still am making up my mind as to what I want, LOL!
There are several things I am shooting for:
1. I'm older and I like simple. Not "simplistic" but something with low maintenance and lookup up stuff. I'm fond of comparative die mechanics (no modifiers). The active player rolls a die the defending player rolls a die and you compare the two for the effect. This comes from my love of the Dirtside 2 mechanics, where using polyhedral dice yield some simple but elegant mechanics.
2. While I will not call it "realism" (how realistic a game set in the 40th millennia really be?), but I do require that rules address certain things that are generally glossed over by GW games (command control and a proper morale system).
3. Freeform army building. While I like the ease of the old army card building system, it is restrictive. The size of my collection permits very unconventional army types. Mind you, this doesn't mean I don't want an army organizational structure unique to each army theme, but I do want the ability to define those parameters easily.
4. Rules suited to "epic" sized games. I can play "very" large games. With the exception of SM2, most GW epic rulesets look like skirmish games to me. I like BIG. So any rules must suit sizable games. Easier said than done.
I borrow (steal) liberally from a lot of game systems. My favorite two being DS 2 and original epic (SM1/AT).
I'm still mashing together different mechanics. Some don't fit well and need a substitute/replacement. Lots of experimenting to do.
Also, being very "rules fickle", I am not sold on anything I have now and still look to heavy modifications of the original AT/SM1 system as a possible alternative.
I think the best way to describe the current "rules war" is whether to dump the d6 (or use systems of multiple d6's) or go full polyhedral (the midway point being using a single d10 system for mathematical ease).
I think you can gather its quite a mess.
