OK, so I'm running a relatively low-powered game, core SR4A book only (the splats are getting released a little at a time to simulate the progression of SOTA). Dice pools are limited to 16 dice, runners aren't twinking out specific skills, the fastest guy in the group as 3 IPs and everyone else has 2, ballistic armor ratings are in the single-digits, wireless isn't universal, and so forth. Very SR1/2 feel. So far, it's worked pretty well (for those of you who remember your older modules, the runners just found Madame Ullishia's corpse in their search for the necklace "Blood"). However...
1) Knockdown. Take your Body or more damage in a shot and automatically fall prone. Well...everybody is getting knocked over. PC, NPC...doesn't matter (they don't have a Troll and haven't gone up against one yet). And frankly, that simply doesn't happen. It's breaking our suspension of disbelief. It's the whole "automatically" bit that's getting us. We generally feel that there should be a test of some sort to avoid falling prone if you take more damage than your Body rating. Assuming I institute a house-rule along those lines, am I going to throw anything seriously out of whack?
2) Stick N' Shock. OK, this crap is flat-out busted when it comes to game balance. Right now, we're in kind of a detente where "GM won't use it against the players if the player's don't start using it heavily against NPCs". Aside from arbitrarily giving everybody in the game world either 30 free rounds of S'NS, or Rating X Electric Resistance, anybody got any good ideas about how to deal with this? My players through the earlier editions of SR went out of their way not to use broken stuff they found in the system (or read about on dumpshock), but this stuff has to potential to become a real problem, and there isn't a good way to keep PCs from getting it that doesn't feel excessively arbitrary. Combined with the low-powered, low-optimization game we've got going, this stuff blows people out of the water. How do you folks handle the stuff, and/or given a game in which splats and high-dice combos aren't in play, how would you handle it?
