lol , ok i admit i do not have bf2142, i play the demo of it, and i played the demo of bf2, and in comparison bf2 is much beter( i know ull say the demo is not the same as the ful version, but)gameplay wise 2142 is a bit more hectic, and most of the time unles ur playing as a sniper, or have good squadmates that work in a team and heal others u cant last long enought to kill more than 2 ppl before u die or are barely alive, the tian mode is ok in 2142, but the overall feel is much beter in bf2, and i guess the use of "terain" is beter in bf2, the buildings and all, they just seam to be more "normal/realistic/useful"....thats just my feel for it, others might differ, thats ok
