Well , I did love NS (I am a constie , paying $20 US for the silly icon , lol)
But seeing Flayra haven't get the official website fixed for like almost two years, I am kinda disappointing
For RTS + FPS style game , BF2 copied it quite well (Except the commander , still not able to build stuff , but good enough to drop supply boxes and UAV ...)
Just like DoD -> DoD:Source , once they asked for people to pay for it
the player bases goes smaller (Source Engine quite a system hog .....especially with HDR effect enable , my 6800GS lags like hell in DoD:Source . Even I bought it retail DoD:Source , I don't find it fun to play as it LAG likes hell running on my PC , I am running with "Auto Detect" setting , HDR Enable , I MUST turn off HDR effect and set everything to LOW @ 1024 x 768 to get > 30 fps running on my comp , A64 3500+ 2GB RAM and A 6800GS can't handle it wtf? )
If Flayra wants to release NS:Source , they better make sure not charging it a lot ( Likewise DoD:Source , there are servers but NO Player ......) and hopefully the game itself is not demanding as hell .....
