Total War Warhammer is great for “watching tanks go boom”, but it has a pretty steep learning curve if you want to play well.

The stats on units, spells, and abilities are comprehensive, but not necessarily intuitive to read. It will take a while before you can tell what’s good just from reading the stat card.
You’ll also be spending plenty of time on the map screen, trying to figure out which building to build where and how to use that weird faction-specific resource you keep earning.

It’s not cheap either. You have to buy the older games and dlcs to use the factions that came with them, and most of the most interesting lords were added by dlc.

All that said, I love the game and I think it’s a really fun strategy game. Once you understand what things do, the battles are pretty simple, and it’s really fun to blow up a unit with a magic volcano or charge your army of tyrannosaurs into a horde of rat men.
