The experience of developing Overwatch is very different from that of other Blizzard games; it’s a new IP for the company, and it’s a different genre than any of its predecessors. Designer Geoff Goodman recently answered several questions on the game and its development process, explaining that the team isn’t worried about specifically bringing in a number of characters, just about making the best possible game while adding as many playable characters as possible that make sense while being fun to play.
Goodman also addressed some of the balancing issues between characters and playstyle, noting that purely melee characters have been challenging to design while every character offers some degree of hybrid option for play. The team also doesn’t have any plan to allow community modifications at first, but given the long-standing tradition of community mods for the company’s games, it’s something to consider for the future. Check out the full interview for more details; it’s got a lot to say.
