Winter!: Prepare for holiday gaming!
The Gears game that got me hooked on the series was definitely 2. I didn't even Gears 1 when I played 2 but by the time I had finished the campaign I had bought the first so I could be fully up to date on the story and the characters. While Gears2 didn't do anything too different from the first, it is a much more polished and complete game than the first one. The maps are bigger, the enemies badder, and the story much more complete. Even the multiplayer, which saw the biggest changes made, was a blast to play. The best game in the series in my opinion.
