Blizzard: "We are definitely open to cutting units" in Starcraft II

Blizzard's David Kim indicates the team is more than happy to axe new units if they create balancing issues in the game.

Speaking to PCGamesN at gamescom 2012, Kim was brutally honest about the difficulty of adding new units. With too many, the game might become overcomplicated.

"There's a set number of units that should be in the game, but we just don't know 100% what that is. Initially in Wings of Liberty we went with 13-14 units, which is similar to what Brood War had. When we started exploring a bit more we tried to stick to that rule, but when you're taking units out and putting new stuff in, there are some problems. Wings of Liberty is pretty solid in terms of each unit being useful in a certain scenario - we tried saying, well what if 15 is the right number, or 16 is the right number?"

"After trying it out, we think it's okay to add a couple of more units, but at the same time we don't want it to go too out of balance, so that it becomes too complex. That's something we have to watch for during the beta, and really make sure that the number we have right now is good for the game."

With the beta in mind, Kim says any unit could get the chop.

"We are definitely open to cutting units," asserts Kim, "depending on how the beta goes."

He also revealed the Heart of the Swarm beta will run for an undetermined length of time. "As long as it takes us to get the game where we want it to be."
