I still think COD is closer to R6 or the like for realism, and not at all like Quake or Unreal Tournament. Still somewhat arcadey, but close enough without being a bore.
Red Orchestra was awesome for the tension…you had to work to stay alive and go on a killing spree. Plus there were vehicles, not everyone got the SMG (most just got rifles, a few semiauto rifles, and maybe something else), big maps, etc. It slowed the gameplay down and make you try to stay alive. COD1 & 2 do encourage more blind charges. It seems like you just chase each other around the map as the spawn points move, it’s really fast and repetitive, so it gets old quick. I’ve tried to go back a few times recently, but it just isn’t the same. I have fond memories of COD1 though, charging in commando, blowing dudes away and picking up their guns so i don’t have to reload. Fun game.
Battlefield 2 is a bit more arcadey, but I enjoy the team tactics, vehicles, squads, persistent stats and unlocks, so it’s got a lot going there.
But for arcadey fun I still turn to Team Fortress 2. That game is awesome and not realistic at all.
Looking forward to Left 4 Dead soon. Check it out.
