UPDATE: All this served me and my gaming group well in the period between the release of SWADE and the TLPG Update Doc officially posted by the PEG team. As of this update we are, with all the other Savage Rifts groups on the PEG forums, helping to playtest the latest official rules and have cheerfully tossed my interim house rules aside.
Well, I did it, made a PDF of what I’ve put together of my SWAdE-based Mega Powers house rules to hold me and my group over until the official stuff eventually gets released.
These differ significantly from the first draft I posted here last month.
As I update it further (which is bound to happen considering how much feedback I’m getting from my group), I’ll post new versions.
