No one will probably even read this but I've been thinking a lot about CoD vs. BF recently and hey, NeoGaf should be the one place you can talk about this without bothering anyone so here goes. Here's my thoughts on all this.
I got into Call of Duty with Modern Warfare. I'd played the others before but I'd never played their multiplayer components. I got a good taste of MW1, and then MW2 came out and I played that endlessly for the next year. Was pumped for Black Ops. Hated it after a month or two of initially having fun, and dropped it for Bad Company 2. Recently I've been trying to get into Black Ops with different weapons setups. I've regained a bit of enjoyment by finally being able to post good K/D in team deathmatch thanks to some GAF loadout recommendations.
Obviously today's Gamescom MP footage from Battlefield 3 is really intense and looks like a blast - almost a religious experience! So much crap happening, such good graphics, and such a grand scale. You'd be a stone cold beast to not get excited about that!
And after spending a lot of time with both franchises I think that Battlefield is fundamentally the 'better' game in terms of realism, fairness, depth, graphics, sound, and so forth. At the same time, there's a sort of primal appeal to the ludicrously fast gunplay in Black Ops that's also pretty hard to deny. It's not as rewarding since even a big 30-5 game is just a 8 minute rush and is quickly forgotten, but when you're in the zone and racking up kills it's addictive.
I think that Black Ops was a huge step back from Modern Warfare 2 just because they narrowed the spectrum of viable combat options. Treyarch was trying to balance everything out, but they neutered the fun and the 60's setting nixed some of the more fun future-tech options. In Modern Warfare 2 people could dominate with a lot of different setups - knifing, sniping, shotties, assault rifles, smg classes, lmgs with FMJ or even weird combos like riot shield and C4. In Black Ops pretty much the only way to be competitive is with an assault rifle (preferably suppressed). It gets old.
So that said, I think Modern Warfare 3 has the chance to undo the restrictions that Black Ops imposed on the series (bring back heartbeat sensors, stacking streaks, secondary shotties, riot shields, machine pistols, EMPs, and all that shit, it added variety!) and be sort of a return to form after a serious misstep. Black Ops burned me enough that I'm not Day One on Modern Warfare 3 at all, though - I'll use my friends as guinea pigs. If the netcode and framerate is better, if the weapons all have their places and there's a bunch of different fun options, I'll buy it.
But Battlefield 3 is Day One for a few reasons. First, because they're doing a beta. I love that sort of transparency! If Modern Warfare 3 would let me see the game before expecting me to put most of a day's pay into it (I'm a student), then I would probably Day One it as well. Second, because I think ultimately Battlefield 3's slower pace is less frustrating and the focus on team gameplay, objectives, and longer match times is more rewarding. You can't beat that high of winning a 30-minute long rush match in the final seconds.
