Henry Gilbert: When it first launched, I was pretty dubious of the 360’s software line-up. Perfect Dark Zero was a bust, games like Gun and King Kong didn’t look all that improved compared to the Xbox versions, and the less said about Kameo the better. Just as I was deciding dismiss the 360 until the “real games” started coming out, I kept hearing from friends and reading online that easily the must-own launch game was a title called Geometry Wars. The best part? It was only five dollars.
