Well, personally as an everyday common friendly neighborhood RtCW player, I have to admit, that I usually don’t care what mod the server is playing.
I usually look for an RtCW server with players and I join. I’m sure they all offer great features, and in the game industry ideas do seem to meld together. Hasn’t really been an original game idea in quite some time… ET did a great job at implementing some unique features. But still, engies build, spies stab…
One feature of Shrub that does stick to my memory is the syringe kills. ET already has the stat slot for it. I nice little poke to my nemesis would be fun 
But from what, two years of playing these mods, thats about all I remember. Poison syringes. I would like to see the mod creators come up with something new, not just carry over stuff from RtCW.
For example, limit the number of covert ops on a team. Whomever can do that would be my hero.
Or another thought, how about a mod to warp us out of the WWII era. sigh way off topic, but MOH ( played multiplayer for ten minutes then retired CD) is coming out with yet another WWII themed game. Enough already!!! I digress.
Instead of arguing about simularities, be the first to come up with something unique. Personally I’m praying TF2 comes out with HL2 on October. Its time to leave this WWII era to rest.
:blah: )
