What the fuck are you smokin'?
Halo has always been innovative. Each of the original Halo games pretty much defined FPS on consoles. They defined the online console experience. They defined true post release longevity for a console series.
You know something? Each main Halo game feels like a damm Halo game. The feel of the game didn't get in the way of the innovations each title brought to the genre and the series.
If you think how a game feels or controls is somehow restrictively tied to how innovative a game is, then you're smoking some really powerful stuff.
And mechanics? You're saying Halo's gameplay mechanics are outdated too?
You should probably just leave the thread at this point before you are smothered by your own stupid comments.
