I was going to pick the game up release day but decided against it since MW3 was such a... disappointment... and Black ops 1 was kind of bland. I figured that waiting for a few days and then asking would be the best course of action.
I'm only concerned with MP and zombies. Are they any good? Does any weapon or class really stand out as overpowered right now? Hows the hit detection/lag? Do you see yourself playing the game for more than a few days?
There are two kinds of people. The ones that ask questions to find answers, and the kind that ask questions to make excuses.
No OP weapons IMO. Connections are questionable sometimes. Even a seemingly perfect 4 bar will leave you scratching your head as to how you lost to a guy who you were ready for and shot at first with perfect aim.
If you're a TDM fan, you're better off waiting until getting Ghost before trying it.
People are strange, when you're a stranger, Faces look ugly, when you're alone
IMO it has potential to be good, but is absolutely horrid at the moment. You'll most likely do bad if you have anything less than a full bar connection. Rampant head glitching players, many with modded controllers as well. And as per COD tradition, it's just a camp fest OR run and gun. If you try to snipe or play conservatively you'll get gunned down by someone from behind or they wait for you in a corner on the other side of the map. If they somehow patch the lag issues and a couple other things the online will be okay. Campaign and zombies is good though. I'd rent first.
