Here is how I would introduce people to Noise:
There will be servers you can't get into without paying money you will never have. That's fine. You don't need to be able to get in everywhere. You just need to be able to get in SOMEWHERE, and make it really really hurt when you do. That can be:
R&D: Medium + IMP/ID ability combo
HQ: Lamprey + IMP
Remotes: IMP assets and critical upgrades. Obviously get points if they play too fast.
They need defend everything all the time. That takes a lot of money and ice. Parasite and IMP let you deny them on both fronts (Lamprey and your ID also help). Additionally, your ID pressures Jackson usage on archives. This forces them to make remote plays you can bust with your AI breaker (and D4v1D), or break them rezzing ice to defend it. Heaven forbid they play passively against your ID. The longer they wait, the more juicy HQ gets, the denser R&D gets, and the richer you get. So many games see my opponents with 2 points and me at 0, them making a remote play for the 2nd time, me going after it, and them going broke defending it. This leads to a centrals assault that very quickly closes the game.
