Yes, it's still not difficult to get into a match that's full or nearly full every time you play, or at least it's that way for me and the other folks on this forum.
If you already owned this game on a previous system, then log in to your new system with the same PSN account that you used on the old one. Then go into the PSN Store, and on the top right corner of the screen, there should be a button you can click to view your previously downloaded items. Find BF1943 in there, and download it. That way you won't need to buy it again.
