On the comparisons I've made to Illwinter's games, I aimed to create something that would play kinda similar to how the combat mechanically functions.
However, without the grand-strategy multi-battle elements, there is definitely a huge gap in how War Grids feels and how Illwinter games feel.
I use Unity 6.1 and C# to create all my games. If you're interested in game development, I highly recommend the youtube channel Brackeys for beginner-friendly tutorials. That's where I got started.
Thanks for the kind words! I'll keep trying to make cool stuff :)
