However, we were fairly impressed when they showed us that the editor allows first-person game creation. What?! Yes, that even includes details as far down as UI manipulation and an inventory system. That's a lot more than you'd expect from a simple "map editor." One employee-created game was an FPS featuring a very familiar, bouncing-ponytailed Ghost that was created in just a few days.
Blizzard officially put StarCraft: Ghost on indefinite hold back in 2006, and they've been telling us here that it's still the case. Although some enterprising modder/mapper out there might just want create their own version.
