Corporate Town has the ability to wreck someone's economy. But in some decks, it's now mandatory, because of one card: Film Critic. Film Critic is what Clot is to Fast-Advance, except for Argus Security: Protection Guaranteed, Jinteki: Personal Evolution, and any deck stacked with cards with steal effects, as noted in its reviews. It requires an answer, and Corporate Town can be that answer. It also pairs well with The Future is Now to get it when you need it (and not show the runner.) The best alternative is to tag them to trash Film Critic, but most Runners fight tooth and nail to prevent being tagged on the Corp's turn, or possibly Contract Killer (however, that costs 4 influence, requires several clicks, and only hits Connections, although it can also do damage), or Snatch and Grab (but only trashes a connection and requires a trace, so much more narrow.)
Many of those same decks would gladly run Archer, after all, it's cheap, brutally effective, and they have cheap agendas to spare! For the same influence (or lack thereof), they now have Corporate Town - the card that ends their woes against Film Critic, with the ability to cripple decks even if Film Critic isn't a target.
When it's good, it's very good. Worst case, you lay it out alone face down and force them to decide if it's worth the 5 to trash, after spending a click to run it. Best case, you ruin their entire game plan, taking out Film Critic, a loaded Kati Jones, stacked Off-Campus Apartment, Tri-maf Contact for meat damage (maybe even a kill!), stacked Personal Workshop, Aesop's Pawnshop that's literally their econ engine, Wyldside draw engine, Daily Casts before they take any credits, loaded The Supplier, make them use Hades Shard, or Utopia Shard, Liberated Account, Professional Contacts... Kill them all. Film Critic was the tipping point; Corporate Town is now essential in the right deck.
And if you're NBN, you can run License Acquisition to install+rez it for free (even from Archives!), but then they get a turn to take it down before it has its effect. Do note, NBN can also run Character Assassination, or Breaking News + trash from tag.
TL;DR: Corporate Town, tagging them, Contract Killer, or Snatch and Grab. That is, until they print another truly viable resource-hate card. (Having a requirement of them being tagged kind of defeats the point... I'm looking at you Freelancer/The All-Seeing I)
