Frontlines caught my attention the most since its more of a large scale combat, up to 50 players total on the Xbox 360. The game also features a unique system of play, whereby the "front line" of the battle is extended as you capture important points. There is also unique weapon aspects, drones, air bombs, etc. that seems like they will put a nice twist on the battles. The bad side is the game seems to be too fast paced, way to "run and gun", not enough tactical shooting.
Call of Duty 4, as opposed to Frontlines, seemed like a pretty nice blend of game play. Perhaps Dennis was right, I am sure he will appreciate the acknowledgment. I think if anything that will be the title I pick up when I do get my 360, if I get my 360. After viewing vids of people playing on Youtube, my biggest enjoyment may come from the remote charges. Lots of vids of people planting them on cars, then creating massive explosions, taking out the car, and everyone nearby.Time will tell what wins out, or if I even get the 360.
