Titanfall is one of the most anticipated games of 2014. You would have thought marketing it would have been easy, but apparently that's not the case. During a long multi-answer thread on NeoGAF, Titanfall's Producer Drew McCoy revealed the difficulty that not offering single player gave:
"Its 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 also revealed that they approached it with an open mind, after letting people get hands on with the game.
"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 has been under fire lately for revealing a max player count at 6.
To be honest, I've waited a long time for a company to say "bigger isn't necessarily better". It's one of the issues I have with a lot of FPS games online where the maps don't compensate for the sheer amount of players crammed in.
