While Halo, Sega GT2002, and Splinter Cell are super fun, sometimes I want to kick back and do some mindless shooting without having to worry about strategy. It seems that these days complexity and plot are necessary for a killer game... but what if you want a break from that? So, I'm looking for some good suggestions on what I can throw into the console and just have an hour of killing fun? Something that won't grow old quickly. It's a rare game that meets these criteria - are there any on the Xbox? Thanks, Martin.
