I wasn't saying that the source engine has anything to do with this game. I was only comparing the visual quality of this game to games that came out around or shortly after HL2. This game does not use the Source engine.
I just find it surprising that the developer's PR screenshots don't look any better. I'd bet that the finished product a month from now will not look much different, if at all. In the age of broadband, keeping filesize down for a beta seems like a lame excuse.
First, Titanfall uses a modified Source engine.
Second, I'm not sure what your goal is here. The devs said it directly via twitter. There's nothing more to discuss until the game ships.
Two problems with this.
They could have made a pilot and infantry class.
6 pilots and 6 marines per round.
When it's time to switch sides, the pilots go to marines, the marines go to pilots. Or something along those lines. Or how about doing without them all together?
They also could have made the maps larger to support more REAL players.
Why the hell would I want to run around as a normal soldier when I can play as a Pilot? You're missing the point of this game. I also doubt the 6v6 has anything to do with the map size. you could easy put more players on the maps that we've been playing. But that's not what they wanted to do.
