Not plenty at all.

Are you cringing yet? =D

I'm not so sure. Different projects, different design teams and different people in charge. Additionally, Dusty Monk said that they were deliberately using a stylized heroic art style like WarCraft. For what it's worth, he also said that the last build looked a lot better than the screens and art that have been released.

Ultimately, Halo is a somewhat serious science fiction game that draws tons of inspiration from Aliens. It's hard to see that heritage in Titan's concept art. It just looks goofy and kind of generic, with a few icons from Halo thrown in.

: But with that said, an MMO format just doesn't fit with a lot of core Halo
: elements, and from a lore standpoint they really arrest momentum (look at
: what happened to Warcraft) so I'm supremely happy it didn't come to be.

What gets me is the psions. Like I said, Halo is a rather grounded sort of space opera that draws inspiration from Aliens. There's some oddball stuff in the first games and the first two Nylund novels, which was what was out at the time that Titan was in production, but there was absolutely no mention of ESP or psionics or any other kind of space magic.

Dumping psionics into Halo so that wizard classes could be implemented would've been as big of a genre shift as turning the UNSC into a federation of alien races. I don't know if this game was set to be in the far future of the Halo games, but it would've run roughshod over Bungie's territory. If they knew about Titan, it's no wonder some of them were pissy about Halo Wars.
