Well, I know I am one of the last hold outs over at SHO. I love Socom still and have more fun on my Socom nights then COD4 nights. Respawn and FPS view kills that game for me. I like a much more real battlefield tactics type of game, NOt some fast paced run and gun thing that feels like a respawn room Halo game. I disagree with Path's "trade off"... Longer games? I had a almost 45 minute game on Water Works last week. Heart pumping every round, intense... never do I get that with COD4. There was NO lag the whole night and no dropped rooms.
I think it does come down to what's more important to you. I could care less about graphics, (I grew up on Pong and Atari 2600)... when it's not the right game play, lobby system and view. For me, Socom is where the fun is and the reason I still love to log on and play there... Can't wait for CF... then I can actually play with all my clan mates again. LOL
