Halo 3 gave me reason to own a 360, it allowed me to meet people who I never would have otherwise, friends I wouldn't trade for a position as president, great memories so numerous I am unable to recall them all, an experience that was both casual and competitive, responsive, and without a moment where I thought "that shouldn't have happened" (unless lag was involved, in which case it was entirely my fault and no one else s). From the noob beginnings, to 1st customs, to the making of "fat kid" to races, tank beats all, minotaur, and some many here won't recognize. The chopper was by far the most unique vehicle in Halo for how it works, as well as making good fights in matchmaking, as well as unique minigames in customs.
Halo Reach brought new cards to the table. Maps were more vast and easy to make, combat was more diverse and dynamic, yet still on an even playing field. The customs got crazier and more polished, invasion was my favorite in it for it's asymmetric gameplay, structures so massive I swear someone broke the game just to do. I loved flying through the skies with a jet pack and in a falcon, I loved rolling around with evade, or driving around in a revenant. Whether it was out smarting coppers in hot pursuit, leaving people in the dust in the more elaborate tracks, or whatever crazy thing was going on, It was here that i honestly thought customs could not get better.
And while the above is where my greatest love for Halo lies, and many call Halo 4 a bad game by comparison, I wouldn't be here writing (or typing if you want to be technical) all of this, if it wasn't in the state it was, I would be out there somewhere drifting, and so long as this site lives, those memories will continue to be made, and my love for Halo will endure. Sappy, maybe, but true nevertheless.
