No. It was a MoH replica.
It was miles ahead of MOH.
Allied Assault was one of my biggest FPS favorites that was snuffed out by CoD 1. At the time being able to aim down the sights was a huge step forward and the campaigns were much more action packed. It also felt more fluid and responsive than Allied Assault which meant overall a more fun experience. This was back when Call of Duty appeared to be one of those "indie" games you see now. A silent, relatively unknown game that tried something new and hit it out of the park. It didn't look like it had the polish of MOH, but it had it where it counted.
UO took it up another notch with various additions and vehicles/stationary guns in MP. UO's multiplayer was so dynamic it's a shame more people didn't play it.
CoD 2 wasn't as deep gameplay-wise, but it was a nice transition to next-gen graphics. It also had some of the weapons from UO but a lot was left out. Still the game was fresh and MP was a blast.
I played CoD 3 briefly on a PS2 and it was decent for a console shooter, I think I had more fun playing RTCW on console multiplayer though.
Modern Warfare was IMO the last good CoD game. It's when the series was at the top of the mountain and the only place to go from there was down. Perks, weapons without any felt recoil, rankings/levels, and unlocks were an obvious sign of the coming apocalypse for the series.
I didn't get much time to play World at War but the few multiplayer games I did take part in felt like MW1 with WWII equipment. It was also a mess that allowed sides to use any weapon they wanted, so you would have Japanese running around with Thompson SMGs, or Americans blasting away with an MP40.
Played MW2 on a Steam free weekend. One of the first games it put me in was hacked and I ranked up to 70 in 1 kill. Used a magical plastic bulletproof riot shield and Beretta 92 to screw around and dominate a few rounds just out of pure randomness. The whole game felt like MW1 on steroids. The ranks and unlocks were taken to a ridiculous extreme, the weapons felt even more fake, and so did their add-ons.
And we all know about Blops.
