The lack of single-player in Titanfall has made the game "really tough" to market according to developer Respawn.
Drew McCoy has taken to NeoGAF to say how they have had to take a different approach in terms of trailers to get the game noticed by people.
It's actually been really tough trying to accurately market Titanfall. If you look at what we've done, its a lot different than what most FPS games do. Without a bunch of highly scripted SP moments to recam from different angles, the usual 'movie like' trailer is just about right out.
Instead, we've decided to show unedited gameplay segments that last 3-5 minutes (so far - more footage coming, of course!) to show the 'flow' of the game. Starting as a Pilot, taking on AI and other player Pilots, wall running around a Titan, earning your Titan, climbing in, battling other Titans while stomping on humans, ejecting, etc. There's a huge amount of gameplay mechanics available at any one time, and encompassing them in a few minutes is actually quite hard to do.
He said that this is the reason that they also took pre-alpha builds to places like PAX and Gamescom last year.
Its also why we took an extremely early pre-alpha build of the game to events like Gamescom, PAX, etc. to let normal dudes hands-on time with the game. There's no amount of polished marketing that can replace playing the actual game.
Titanfall is set for a release on PC, Xbox One and Xbox 360 on March 11th in NA and March 13th in Europe. Looking forward to it?
