While I welcome the idea of having a game take place in a historical setting that is usually ignored, I'm also quite sceptical. I mean, WWI (if I remember correctly) mostly consisted of sitting in a trench and shooting mortars and rifles at where you thought the enemy was, and then charging blindly into fire, hoping that you won't get shot, so can you really make an interesting game out of that? It's been a long time since I've played the Battlefield 1918 mod, but I remember that being quite boring.I want this to be good though, it's just that I have completely lost faith in Battlefield after the blurry, crappy mess that was Battlefield 3 (or as I like to call it: Call of Colour Correction: Modern Battlefield). After playing that the series was basically dead to me. To this day I refuse to even acknowledge the existence of Battlefield 4.
So maybe Battlefield 5 can bring this once great series back to my heart!
Well, for one, Verdun is interesting game (interesting enough for me to sink 170 hours into it), so you can make interesting game based on ww1.
Also, like ww2 wasnt just Stalingrad, D-Day or Berlin, WW1 was more than just western front. And even western front saw lot of interesting and mobile action- though true, mostly in 1914 and 1918. But other than western front, eastern front basically didnt stop moving, balkan front, african front was literally british armies chasing german army (which managed to kick british butts quite few times), alpine front and short-lived asian front. Heck, ever heard of Arabian Lawrence? Middle-eastern front was extremely mobile.
So yeah, western front was mostly sitting in trench and charging on big events, but other fronts were way more open (well, aside alpine front, which really was even more sitting still than western front)
I know you didnt complain about this, but i want to put few other issues to bed here: its commonly tought not many weapons were present in ww1 (in variations that is) and also lack of vehicles.
Weapons: while indeed, most weapons were bolt-action rifles & carbines, there were several types of those, each with pros and cons. Plus pistols & revolvers (again, several types). Oh, and flamethrowers. Late stage war, even trenchguns and SMG-s appeared (probably best known one is BAR 1918, which was widely used in ww2 as well).
As for vehicles. Again, suprisingly large variety- while indeed tanks were mostly big and bulky (at least ones most used), Renault FT17 (first modern tank, also was in ww2) was used in war late stage. But there were also cars, trucks, horses and several types of planes. Planes are probably largest in variety, as planes were designed left and right in ww1, biplanes, fokker triplanes (like one used by infamous red baron), bulldog fighters.. Heck, even full-metal modern-looking bombers were developed (and used) during ww1. So there is tons of stuff
And hey, if someone thinks its not enough, then DLC expansion can always take place in Russian revolution and accompanying independence wars (i seriously hope that- to see estonian independence war battles in DLC expansion)
