343 Industries isn't worried about franchise fatigue with the Halo series, because it's not just pumping out sequels.
"I think that people get bored of things when things get boring,' 343 Industries' Frank O'Connor told Ausgamers.
O'Connor pointed out that there are over 100 different Mario games available, and people still enjoy them.
"So if these products keep bringing something fresh and keep bringing something new... you know, Halo’s got five or six games total," he said.
"We always plan to make sure that we’re innovating and that we’re putting fresh story in and that we’re putting something new in there and that’s how you avoid franchise fatigue. I think if you start making boring stuff, people are going to get bored and that’s what you have to avoid."
"There’s no such thing as phoning it in for us," colleague Chad Armstrong chimed in.
"We’re not simply like 'you know, we’ve got seven different Halo titles out now, we don’t really have to think about it because people will buy anything with the name Halo on it'. Every project, from the beginning up to the end, is something that people bleed for really.
"We work really hard and do everything we can to make sure that quality comes first. Our primary goal is to continue to make great games. The fact that they’re all in one franchise just makes some things easier and some things more difficult."
O'Connor also noted that despite its status as a flagship franchise, Halo doesn't come under pressure from Microsoft executives.
"The cool thing about Microsoft period, whether it’s Bungie or 343 or Turn 10 or whoever, they just respect what we do and what we think is best for the Universe. So I don’t ever have executives from Microsoft ordering us to do certain things or build certain products."
