PlayDevil has been playing Titanfall for a few weeks and has reviewed the game now the servers have settled and the first couple of patches have been released.
Here is a snippet:
"The greatest achievement of Titanfall though is that levelling is possible for anyone. The AI is mostly easy to kill, and whilst killing enemy human players and titans is far more rewarding (both literally and metaphorically), progress is therefore steady, regardless of the skill of both yourself and your opponents. This removes a lot of the frustration of other shooters, and meant that I actually felt hooked in by the levelling and customisation for the first time in this kind of game."
