Finished the game yesterday. That was an awesome final 2 levels for both campaigns. Especially loved the Aerialbots level. My biggest gripe is the length. I want more!!! The story told is a small portion of the story, but the character chatter covers a lot of character backstory which was nice. The story told is a little too intimate. If there was another say 3 more missions for each campaign covering just a handful more of characters I think it'd be perfect. Also the final battle I was expecting didn't happen. So it kinda felt a little empty and cliffhanger like without *THAT* battle.
I thoroughly enjoyed it. I doubt I will play multiplayer outside of co-op though. So half the game is lost on me. I can highly reccomend it to any TF fan. For gamers this is a good diversion if a bit short, but there's multi, so that can pad out the value of the game for you. But for the price of a Voayger + $10, you can't go wrong. Nicely polished with just a couple of annoying bugs, I'd say this is the best TF game out (although I've never played the Armada game on PS2).
