A good game needs a fun gameplay style, good characters, good atmosphere, and brilliant story. World War 1 had no outstanding people of interest, the atmosphere was dull and depressing, and as far as the story goes, it was probably the most uneventful wars in history. It wasn't exciting in real life, so why would a video game be made? Level 1, you wait in trenches, level 2 you die.The End.
True, a good game needs those three concepts to properly flourish. But it would be incorrect to write out WW1 completely, this is the war that made the 20th century. When you say 'people of interest' you mean important leaders and generals, WW1 was filled to the brim with them. General Haig, Kaiser Wilhelm II and even Winston Churchill, who at the time was lord of the admiralty, the main supporter of the tank and the mastermind behind the Gallipoli fiasco. If by 'people of interest' you mean Rambo-like figures who achieved far more than the average soldier/pilot then look up Alvin York and Manfred von Richtofen on wikipedia, in fact here are the links.

And the atmosphere being depressing and dim really only holds true if you are solely going to focus on the western front, where it really was quite miserable. The Battles in Eastern Europe and the Middle East were worlds apart, involving dramatic manoeuvres and large scale battles and sieges over a wide area. And even if the western front was grim, isn't war in general? Whether I would be fighting in France in 1916 or 1944 it would still be a grim affair of death and slaughter. More people died in WW2 than in WW1, if you care to remember.
The excitement could come from the atmosphere, the idea that you are constantly under attack and that feeling of dread of the coming fight, instead of elation at the chance. A WW1 game, if done right, would be a very atmospheric thing. And most defiantly not repetitive, as my hypothetical game above shows that variety is possible, if not easy, in a WW1 game.
Another thing. WWII is an amazing plot because of Hitler. Deception, betrayal, bigotry, ruthlessness, and military genius... it's like if Hannibal Lector is President. Hitler's an evil leader that writers couldn't dream of conjuring up. Who was the evil tyrant behind World War 1? There WASN'T one. There's nobody to blame and I'm sure the thought "I'm doing this because..." is sure to be reacquainted with the player after the plotless fun bliss (a.k.a. TF2 Syndrome) isn't around to keep him away.
WW1 started when the European alliance system, a sort of pre-cold war MAD, blew up. Fear, distrust, and ambiguity sparked the whole thing off, that had been brewing for far longer than WW2 had been. And you are correct, there was no evil tyrant behind any of the powers, and that is a bad thing? The world isn't a cartoonish perception of something is black or white. All sides of the war were grey, neither morally just nor unquestionably vile. Stark moral contrasts get quite boring after a while. Introduce some ambiguity, make the player thing "Why am I fighting", as potent an anti-war message as any nuclear device detonated in an unmarked Arabic city.
More than that, what CAN you do? Basically, imagine a game of Gears of War 2 where everybody on one team is huddles behind a single chest-high wall, as does the other team on the other side of the map. Now imagine that everyone on the map has nothing but a lance that has no chainsaw. What happens? Everyone leaves because they're bored. It's a bad idea. World War 1 wasn't cool.
See my hypothetical game above for an idea of the variety of what is possible for singleplayer. Multiplayer, to be honest, has never mapped reality very well, with the whole idea of running around and blasting away without thinking.
