It was definitely a big source of inspiration, although I really disliked how swingy the RNG was in practice (kinda had to be though since it was table top).
XCOM as well as a few other strat games were also something's I pulled from.
I got a few other units in mind for the game that are all partway through development but it's just finding the time to put out updates.
If you are gonna try the concept yourself I'd suggest building a strong framework for multiple gamemodes. While my workflow for new characters is great, new gamemodes especially with my AI is somewhat cludgy as scope creep happened a bit. If you want to take it to the next level let players design their maps and save them, add props, etc. Was way beyond my level to make that so I went with procedural generation.
