Nope. Because Halo (and 2 & 3) offers nothing that hadn't already been provided by PC FPS titles.
Like pretty much all good titles the Halo series added a few interesting refinements (2 gun minimum, recharging shields) but nothing groundbreak in terms of FPS or online play per se.
It did raise the bar through the roof for FPS/online on consoles though, however in terms of recent big FPS titles I still see more influence from PC roots than Halo directly.
Try to be reasonable... its easier than you think...
