Yeah, I had to figure out what it really is from Wikipedia and my two reactions were:

• Ubisoft has a ‘universe’? Huh, I guess, they do have a few franchises there.
• That actually sounds reasonably interesting. At least it’s not just yet another uninspired shooter.

And like, yeah, lacklustre marketing puts it quite well. I had heard of XDefiant before, but all I got from that was that it’s a shooter, which made me fall asleep immediately.
Had they sold it as “You ever wanted to pit the Splinter Cell guy against the Far Cry bandits?”, I would have at least remembered it.

But to be fair, a lot of games are currently coming out. It is difficult to be seen for pretty much all titles…
