Yeah, so after four days of ZERO matches, sometimes after up to 15 minutes of waiting in matchmaking, I'm done with this game. The campaigns are cool and all, but multiplayer was the main draw for me. Just returned to Gamestop for in-store refund credit and applied it to Dragon Age: Inquisition coming next week.
I never thought I'd sell or trade in a Halo game (still have Halo: CE, Halo Anniversary, Halo 2, Halo 3, Halo 4, and Halo ODST)...but there it is. I might pick it up later on down the road when it's on sale around $30 and matchmaking is solid. We'll see.
