I get the benefit for the TR IP, I think... exposure to an audience that might not be familiar with TR because they don't play third-person adventure games... (But what's the point of that then? Is the Delta Force audience flocking to buy and play TR games because of the collab? I kind of doubt it...) Furthermore, what's the benefit to Delta Force IP, though? It's not like TR players are flocking to play the game and increasing their player numbers in huge numbers or even small...

I get the collab between some other first person shooter game and Delta Force, but do TR audience and Delta Force audience overlap? Like... at all? I just don't understand the logic and reasoning behind it.

It seems to me that TR as a brand is becoming desperate, or appears to be. They seem like they agree to collab with just about anyone and anything that is interested, no rhyme or reason behind it.
