Halo was an FPS and a spiritual successor to an earlier series of theirs called "Marathon". The main characters, weapons, and themes of the original game all skew very closely to Marathon.
I miss the Bungie that pumped out Marathon, Myth, and Oni.
(I will look forward to people who were screaming that console makers mustn't be allowed to buy game authors and studios seamlessly turn a 180 if it favours their tribe.)
Myth and Marathon were experiences in storytelling for me however. I even have a copy of the GURPS Myth roleplaying guide sitting on my bookshelf behind me that goes more into the lore of the Myth universe.
Me too! I had so much hope for Oni, but the control system drove me nuts. While it looked great I couldn't play it worth a damn. Maybe that was just me.
There's also tangential evidence that Pathways Into Darkness, Marathon, Halo, and Destiny all exist in the same universe.
And with this recent 30th anniversary event, it also seems like they kind of think of all of their various older IPs to be in a multiverse of some sort.
(And Pathways into Darkness was also an FPS, just like those three Marathon games. Bungie has been doing FPSes for a long time, 100% agree with you.)
