It’s been 8 years since VI came out. That’s the longest they’ve gone between releases since the original. It’s also difficult to say if it’s necessary without actually seeing what VII has to offer. If it’s VI with a new coat of paint, then I agree. But I hope they bring a novel aspect like districts was for VI that made it worth it.
