Man, watching this now... it just hurts.
The whole idea of developing a fantasy-type universe but with a science fiction backdrop is still a fascinating and wonderful idea. Sure you could say the Phantasy Star series did it, but I'd go even further back and say games like the Myst series did this too, obviously with more emphasis on the fantastical. I love this concept in art form, and I remember watching videos like this when Bungie was developing this and couldn't help but be giddy with excitement and anticipation. This video is an amazing watch for their development of concept art.
What happened though? I'll reiterate my theory that there was some big event/shakedown during development at Bungie that had left them spinning their wheels and not properly pushing development FORWARD. It's becoming clear now the lead developers DIDN'T want a concise story for this universe, arguing that you're playing your own character and not one specific one. In so doing, all the story/universe aspects have been left so vague and detached that the result ended up being a very muddled and rather unengaging narrative. Joe Staten leaving Bungie did NOT do them any favors, and I think we're seeing the sour fruits of that now.
The general "foundation" of game mechanics seem there too in terms of movement, weapon handling and enemy encounters. But how did the mission types end up so repetitive and boss encounters so unimaginative? How does a game billed as a "shared-world shooter" and having "organic" cooperative play end up with such limited ways of interaction and manage to still feel quite lonely?
Was this game not playtested thoroughly? Did folks not sit down with it more for than one to hours at a time? Was the dev team a bit too arrogant and thought everything they touched would be gold? Did Bungie spend so much laboring over its playable environments and skyboxes that it ran out of time to make more fun and varied missions and those more or less became a "we need X number of missions by September" statistic?
Don't even get me started about the firing of Marty O'Donnell. These lingering questions still bug the heck out of me, and I'd just love to know what exactly has been going on at Bungie over the course of the last three years.
Of course they play tested it. Their testers know exactly what they were going to be selling. But once the heavy investment is made and a deadline is given, what can they do other than release the game and promote it like it's the second coming of gaming to get huge sales numbers to recoup the investment?
