I like to call BiA a ww2 puzzle shooter.
No negative connotations though. It's just that the "tactics" are more about figuring out how a level works than anything else (some had multiple ways to success though. Especially in EiB) and the shooting elements were seriously hampered by that cover-system. It was more like commanding a whole group from the view-point of one member because even if you fired on opponents whether you hit or not wasn't so much a matter of shooting skills than a matter of the game considering those troops covered or not. It was necessary to make it play out how it did though and it WAS fun. No need to bring realism into this. Accept that it is a ww2 puzzle shooter at its core and then either like it or don't.
Regardless of how you think about its gameplay, it's atmosphere was top-notch through-out. Or at least as good as it could possibly get if you really locked your antlers with the gameplay instead of just enjoying it...
The characters even grew bears over the course of the game!
I played both games on my xbox on multiple difficulties and quite a bit of split-screen co-op with my brother in EiB. Good times.
The only thing I really did not like at all about those games were some of the tank fights. Placing your team somewhere out of harms way, then running around the metal beast until you finally find the hidden fausty-crate was a tad ridiculous and on higher difficulties also pretty frustrating. Sadly those sections were pretty common later on in the game.
It would have been better if you got anti-tank equipment yourself or if you found it way before you actually encountered tanks.
Some encounters were better than others though. The end of BiA1 were you started out on the church tower and then you had to defend its base-level was pretty good for example. Or that mission were you meet your own tank guy for the first time. That one worked pretty well too with the tanks.
I don't think the new one will seriously dissapoint people who liked the first two games. I do however think that it will definately dissapoint people who think that this is going to be a 180
