The combos flow with each other so well and they used the transforming aspect of transformers well. The soundtracks have so much effort put into them, with each song fitting perfectly with each of the character's personality, motives, etc. The cel-shading and animations still holds up to this day (except for most of the pre-rendered cutscenes). Every voice actor brought every character full with life (especially Scott Whyte and Dave Boat). And while the story isn't too deep, the writing itself is fantastic with having the best climax/ending of any Transformers game. Only downside is the short length of the campaign, lack of playable characters, and just the little amount of content you get.
