Despite not being a fan of other Jane's Fighters games, I enjoyed this entry.  The premise is obvious - fly missions in Europe's war-ton skies in the famous fighters of the day.  The format of the sim is similar to that of other Jane's fighters titles - you have a flight panel that's more for show than functional; you have separate pop-up windows for your instruments or to spot and range the enemy; you can click on individual targets and handy steering cues point the way to the enemy.  That said, WW2F is graphically a more modern generation of sim than those like USNF or ATF.  Graphics are more realistically defined, and are more immersive than those games.  The planes (instantly recognizable to any mil/av buff) look so realistic, you half expect to see your reflection in their chrome finish.  Atmospheric effects are clearly superior to the first CFS (which roughly coincided with this game) - including clouds, AAA fire and smoke effects from wounded aircraft.  Flight is difficult even at nominal settings - aircraft here are unstable, and may fly apart if overstressed, or simply fall out of the sky if load-factor isn't watched.  AI is somewhat impressive (I mean, I routinely got shot out of the sky, but I'm normally a horrible pilot), though must be compromised to an extent to fit a game where everybody in fighters will fight each other.  (Case in point being Me-262 jets, which will remain in prolonged combat with prop fighters like the Mustang, even though there principal quarry was the box formations of allied bombers; their acceleration and turning capabilities made them unsuited for dogfighting.)  For its great atmospheric effects, nothing seems to cover up an unconvincing attempt to model the terrain of Europe - although most of your work will be up high.  The campaign mode isn't quite dynamic, but it's not as canned as the one on CFS.
