7. StarCraft: Ghost
Blizzard’s StarCraft series started with an RTS that quickly took the world by storm. But it’s concepts carried the potential to branch out into other genres. Blizzard tried to capitalize on this with StarCraft: Ghost, a stealth action game centered on a Terran Black Ops agent (or “Ghost) named Nova who would sneak around enemy bases using cloaking devices, psionics powers and firearms while tangling with all three races in between.
Unfortunately, what could have given Ubisoft’s Splinter Cell series a run for it’s money wounded up becoming a running gag as StarCraft: Ghost slipped away unnoticed into several delays and reworks. Though Blizzard claims that StarCraft: Ghost hasn’t been official cancelled, too many other sources say otherwise, labeling it as vaporware.
