Edge of World is a beautifully thought-out asset that can have a huge impact on a game. However, it can require some time to set-up and can often be difficult to pull off. But when it does it is highly rewarding.
The key to using Edge of World efficiently is installing it behind as much ICE as you can. Rather than trying to build a server specifically for Edge of World I find it best to install it in a server that has just been freed up with a couple of pieces of ICE already protecting it. And thats where the beauty of this asset come from. The ICE just has to be there, rezzed or not it doesn’t matter. There are few things more satisfying than watching a Runner agonizing over wether to access or not after running a three deep server, you not rezzing any of it even though you have the credits. That satisfaction made all the more sweeter when they do access. Another asset that epitomizes the Jinteki mind games.
Of course this isn’t going to happen all the time and like most assets Edge of World has it’s pitfalls. Without the option to advance, the longer it is sat the table untouched, the less likely it is to be run on and unrezzed assets aren’t much of a concern. A possible workaround for this is to use Tennin Institute: The Secrets Within to try and work the bluff. That’s not to say Edge of World is now taking up space. As an example you can use it as protection for a Shell Corporation creating another hard decision for the Runner. Let you amass a wealth of credits or risk hitting what it is upgrading.
Along with this you are going to have manage your econ correctly. As soon as Edge of World is installed you are going to need to keep three credits in reserve. This is a fair costing considering that Edge of World can deliver a crippling amount of brain damage in a single blow. I would gladly pay the three credits for a single point of brain damage for the permanent effect it has.
