This game is amazing. You can recruit and successfully use almost any army you like.
You can cheese, (unless you don't want to), you can use balanced armies (unless you don't want to), you can play at any difficulty you want to, you can reload saves repeatedly to get it just right (unless you don't want to) or you can play ironman mode and live with the consequences (unless you don't want to), you can spam stacks of fodder (unless you don't want to) or use elite stacks that nothing can beat (unless you don't want to).
You can have whole armies of heroes, or monsters, sisters of avelorn, or necrosphinxes, mammoths, skinwolves, hell cannons, or even elves. Or you can use the salt of the earth foot soldiers bravely battling monstrosities to defend their families or bring peace to their lands, or have them fight alongside elite champions, each of which is worth as much as a thousand regular soldiers.
You can change the game using mods (unless you don't want to) or you can make your own modifications (unless you don't want to).
You can play on easy, normal, hard or legendary, and can choose whether to play battles on easy normal or hard, etc.
You can play as a woman or a man, no matter what gender you identify as, or an inhuman monster or the personification of nature.
You (yes, you!) can decide what parts, units, armies, lords, magic, mechanics or exploits you want to use or not. You can successfully play on any difficulty using any play style and be successful.
Do you want to finally kill every last dwarf who ever fired a cannon at you? You can. (Unless you don't want to.)
Do you want hordes of Bretonnian peasants? You can. Do you want slavering monsters hurtling toward the enemy to tear them apart and feast on their entrails? You can. Do you want an army of heroes to destroy the enemy? (unless you're tomb kings)? Yes, you can.
Do you want to play a difficult game, but have fair battles? Yes, you can. Do you want a chilled campaign but tough battles? Yes, you can.
Do you want to create armies that remind you of your tabletop days? Yes, you can. Do you want to make armies that you always dreamed of having on tabletop but could never paint, let alone afford? Yes. Yes, you can.
All supported by a dedicated team of artists and developers that create in astonishing detail a fantasy world that contributed to our childhood (or not)? Yes, you can. Did you never know about the game until after it was destroyed in a conflagration of dark magic and poor plot, but dearly want to discover it anew?
Yes. Yes, you can.
Because how YOU want to play is the aim of the game.
