This is a thought that emerged mainly from the fact that runs -at least for my group- no longer offer the thrill they used to when first playing Netrunner. There is still the suspense of what is hiding behind that server, or what the HQ run will bring, but when I first started playing, there was also the suspense of what piece of Ice I am going to hit.
Most runs I make now are done after im sure i have the necessary credits and/or icebreakers. A piece of Ice will be flipped, I ll pay the cost and move on. Yes, subroutines will still hit me, but they are not that huge of a part to the game for me anymore.
Adding a new mechanic to it all
So the question is: Do you believe Netrunner could add an interesting layer of complication (but most of all excitement) to a run if a new kind of resource was introduced?
For example, today you need credits to install stuff, but for using Icebreakers? Where's the logic in that? If you had another resource you needed to juggle, something like ram memory, energy, or something-that-actually-sounds-cool, maybe runs could be a little more interesting and risky.
Or from the Corp's side, as it is, it currently costs credits to rezz ice, but actually managing it (meaning keeping it rezzed) could again require a form or resource. Allocating it optimally could keep Ice rezzed, or actually pump its strength, or boost a subroutine of the currently encountered Ice at the expense of another rezzed piece.
Yes, it could be a bit too much, but..
I know, this is hardly something that could be done in Netrunner without fundamentally changing how things work (would almost certainly require a Netrunner 2), but it always struck me as odd that you know, the only thing i need to hack a server is install a program and then keep paying cash over and over. Its obvious that it was done from keeping the game from becoming too complicated, but still... something of this sort could add a lot to a game I already love.
