How is Empire? It's the only Total War game I haven't played.
It isn't great.
CA tried to do a lot of interesting stuff but spread themselves too thin.
Plus, the AI is rubbish and this is a time period that requires an AI to be able to handle formations. Even after multiple patches the AI will still start the "square dance of death" from time to time where you are doing enough damage to their unit they will constantly be reforming rather than conducting a bayonet charge.
That said, it is worth picking up on steam sale for cheap. When the game works, it is glorious. In one turn as the Dutch I had:
Naval battle off the Gold Coast to protect my trade convoys.
Battle in India where my VOC levies were held off an attack by sword wielding (and elephant-riding!) Marathas.
Battle in the Americas against the natives.
Full line battle with artillery and cavalry in Europe against the Austrians as I found myself dragged into a war after one of the German states had a revolution.
Unfortunately, CA seems to have an aversion to history now, and I fear I will never see a 30 Years War Total War game. Pike and shot warfare, the Three Musketeers, Polish Winged Hussars charging against disciplined Swedish arquebusiers. Possibilities are endless.
Lately I've been playing Divinity Original Sin 2 and been enjoying it quite a lot. I played it a bit when it first came out, but built my characters badly and was struggling with some balance issues. Tried it again with some better built characters and the game is a lot more enjoyable, but still has some annoying difficulty spikes and isn't always very clear where you should be going for your level or how to proceed with a quest. Minor complaints really, for a game as brilliant as it is.
