It's Bad Company and 1942 with half the content. May I ask, why? Seriously, was it necessary to have no new weapons at all? The guns are different models depending on your team, but it's the same damage, clip capacity- everything. It's still a lot of fun, but they could have done more.
They ended up removing features for god knows what reason, probably because "mean people were griefing waaah". EA tends to be like that.
Also sea maps are nice but the best maps were always the huge land-based ones, especially whenever bombers were involved for no adequately explored reason. Sea maps were good only because it usually meant there were battleships and destroyers and aircraft carriers to make things way more interesting.
The entire point of 1942 was to goof around, which is why everyone got hooked on it. It's basically the ideal party game, heck I had it installed on all the comps back in the chem society's computer lab to play whenever no one wanted to do anything useful. I think the producers at the time realised that all anyone was really playing the game for was the hilarity, since they added the "Secret Weapons" expansion which added all sorts of goofy features and vehicles and everyone played it to death. Then the old producers got steam rolled, replaced, and out came that stuffpile Vietnam.
Battlefield died at number 2, 2142 was kind of fun as any plain old FPS but it wasn't battlefield.
