BTW...I don't think MS owns the rights to Bungie's earlier Marathon series...so that's probably the best shot for a Bungie series making it to iPhone/touch. And Marathon rocks.
Kind of...but much more...esoteric. You can actually play it for free on your PC (or Mac, iirc). Search out "Aleph-One" online, as that's what the upgraded versions go by. I also think it's available on 360 via XBLA.
there really isn't any point to mouselook in doom - its all on auto-aim. The only game that had properly (imo) integrated free-look into a FPS at the time was System Shock - and it had a steep learning curve for most.
True. I wasn't really insinuating that Bungie made it, I was just responding to how he said "no more Halo", and there have been 3, regardless of who did 'em
