I enjoyed this game's campaign for it's party based rpg gameplay, but I dreaded/quickly grew annoyed by it's campaign rts loop.
What is here is a nice and decently long rpg rts hybrid that continues on with some characters from the spellforce 3 campaign, and I really enjoyed some of the characters again, but some of the new party members were a bit generic. You also have access to mercenaries which you can create, but since they lack the characterization of the established npc playable characters, you'll pretty much never want to use them.

So in this game you'll be jumping between rpg and rts, it's been years since I played the base game of spellforce 3, but this felt like it had like 3-4x more rts, which by itself isn't an absolute game breaker, but the rts in this game is dreadful after easy difficulty, and even in easy difficulty it's a bit of a mess.

On normal if you don't instantly bumrush 4 v their base + anyone else you can get from summons/quickly gained soldiers, because if you don't, the enemy spawns troops faster than you and they'll send them to separate bases so that you won't be able to save both, and if one collapses, they'll keep pushing parellel to you and just attack your other undefended bases even further out. Also losing bases is annoying in longer battles cuz you're pretty much limited to resources in an area so you need to keep other less defended bases up to have a shot.

The most efficient way then is to just slam your head against the enemy main bases while adding any on the way there, and just fighting a small army + towers + the main base directly with just your party. This sucks plainly, but is needed to functionally win, every other person I see online talking about the rts segments normal and up are literally making threads years ago about how it's literally impossible without the bum rush.

But the rpg aspects are fun, and there is enough character to be fun, and there are some choices to be made. (Even if the ending is based on a binary choice at the very end)

I was girl main and I was in an open relationship with the elf girl + had sex with the angsty and tired dark elf man.
Didn't seem to punish me but I could see the other characters being a bit more prude if you date more than just them.

You'll be doing some side quests, getting equipment, going through rpg segments, doing rts, and there is a decently large amount of story here. If you play on easy or just are cracked at rts (if that is even enough), or you just bum rush successfully, you'll probably suffer through the rts segments enjoyment wise and enjoy the rest of the game. Selectively the rts is harder than spellforce 3's rts segments, and apparently fallen god is also easier on rts for the campaign than this game.

I'd suggest it but those rts were annoying asf.
