(I think it can be moved to a devlog)
Possible Game names:
Scent of Death -
Well, in war there are dead bodies so it smells. Not very subtle.
Maybe a more subtle version of this name would be "The Scent".
Flowers of War -
The flowers represent the soliders. As they are human and fragile as a flower.
I like this the most but it's very similar to "war of the flowers".
Mother's thirst -
Kind of creepy, but mother is the nation and land, and the land is being watered with the blood of the soliders.
Grounds of Pride.
Pride brought them to the the battlefield and etc.
Meh, anyway, names arn't that important right now. But it's fun to think about it anyway.
I was going to make a list of pros and cons for your project but you have already made your choice

I would have suggested to start developing the racing game because you said it was a short project, it was a new kind of project for you so learning was involved, and it could have been a profitable project. At the same time you could have worked on the concept of the chivalry games because that one seems more ambitious and cancelling the project could have cost you more.
I'm not excited about these names, flowers is a brave choice but I don't like the "of war", just to be more braver I suggest Ephemeral Flowers which should make sense in english.
