Just wrapped up my DC Adventure game that ran for a year, and from a strictly rules based point of view, I came up with a few things I would do differently were I to do this again.
1. I would definitely go with the alternate 2pp/rank Impervious allows you to ignore up to it's ranks rule. Impervious almost never came up the whole year, even with some of bigger PL guys that the PCs were fighting as a solo threat.
2. I would limit regeneration and immortality both to the same limit as Luck, i.e. 1/2 the current power level of the campaign. I don't really want them to be more expensive or to eat up more of my player's points, I just don't want them to have to be knocked out in one shot to injure them or to sit up from being dead as a move action.
3. I would definitely implement the optional rule from the GM's Guide for having minions "interpose" for their boss unless the PCs have ricochet or something similar. Lots of most of the PCs would rush the baddie while the weakest combat PC would mop up the minions.
4. When I actually want minions to be a threat and not a speed bump or a shield, I would definitely look at using slightly modified rules for the mass combat Forces from the GM's Guide. Even throwing a dozen guys into one "Force" means that they are going to potentially get in a few good hits on the PCs.
5. Really, really have to remember to give solo bad guys more area attacks, especially when it makes sense. I forgot to do this through a whole fight with Darkseid, when power stunting his Omega Beams into an area attack would have been pretty scary for the heroes.
6. Area attacks? Instead of having the victims roll two checks against the area attack, I'd have the person making the area attack roll 1d20+area attack ranks to determine if that is higher than the Reflex defense to begin with. I kept forgetting the first check and my players always wanted to roll something for an area attack, so I think I'd embrace it.
That's the main stuff I can think of off the cuff. Lots of fun, but after a year, it's easy to see where I'd do some fine tuning.
