They are both WW1 Sims...but there's where the similarity ends.
I have to land on the same side as Fortiesboy here..in that "In the absense of OFF it would be great"...but OFF is here, and I just can't see me making a switch...OFF has just too much going for it...the campaign is so damn realistic..and that is that really.
I can't help feeling that FE is too shallow (and I dont want that to sound derogatory to FE..it has a community of avid FE ers who would take issue with that comment)...but thats just how it feels to me...and Siggi is correct..eye candy is one thing...but again, as Olham says...there is plenty of that in OFF too...so, OFF it is for me...but I hope the FE guys enjoy their sim as well
