Oh god yeah. Playing MW2 makes me appreciate KZ2 so much more. The maps are infinitely better. The rotating objectives keeps the games fresh and interesting. MW2 modes are just boring. MW2 feels like IW tried to make the cheapest online shooter ever... and they succeeded. Hate the direction they went in from CoD4. It's just a camp fest of people trying to get the overpowered killstreak rewards.
Guerrilla Games, do NOT look at MW2 for any kind of inspiration. You got the basics so spot on with KZ2. Just build on that. Take the feedback to heart and build KZ3 on DEDICATED SERVERS, add a party system (one that isn't completely broken like MW2). Take a look at the classes. Get rid of Assault/Boost or at least stop Boost being able to be swapped with other classes. Bigger maps! Maybe some character/weapon customization. But just stick to your own vision for God's sake. You have your own fan base, your game appeals to a lot of people who don't like other shooters anywhere near as much. Just build from there and try and bring in as many people as possible, but not by ripping off MW2. Urgh. You'll lose more fans than you'll bring in.
Why? All your friends left?

Well I'll be back playing KZ2 soon. Don't really like U2 online. I may play it now and again but certainly not long term. I want to get to the top level in MW2 but I don't particularly want to play it anymore. BFBC2 Beta is
awesome but I dunno how long the Beta will last and have to wait til March for the retail release. I want to get up to 600 hours in KZ2 before calling it a day. If it's just me from GAFe playing I'll just chill with some Sniper action.

Never gets old. <3 KZ2.
