Here is an idea for the game...
Tower defense mechanic like plants vs zombies but Vruk's gob children are like the plants, If they die in battle Vruk just need to make new ones (Realistic to goblin's lore, right?) and humans and other monsters are like the zombies.
Vruk needs to defend his goblin home from them.
Different women make different types of goblins for example a witch can make shaman goblin that can use magical projectile or ork women can make tank goblins etc.
I have been dreaming for a game like this for a long time so, KilljoyTRV if you are reading this really give it some thought and if you are struggling to come up with ideas, I hope this inspires you to continue making the game .
