I'm really, really loving Transformers: War for Cybertron. I've always been a fan of Transformers and WFC is just an amazing adaptation.
However, I felt that the storyline missions weren't broken down enough. While I have no problem with games with length (I mean, who doesn't like more gameplay?) but the missions were ridiculously drawn out. If they had split every mission into two missions, I think that'd be better and more approachable, but it's hard to play campaign in short bursts, as chapters are widely spread out and the missions themselves take hours.
Other than that, and some balancing in the multiplayer, there is absolutely nothing wrong with the game. I love how they had less widely-known characters, and each has a familiar, yet distinct design. I'd like to see some DLC containing extra chassis for multiplayer, and a sequel wouldn't be too bad if they were really dedicated to it. Transformers: Year One, anyone?
Also, BLAM!
EDIT: I just realized I was signed into my old account that I thought I had lost.
Guess not.
