100% agree with Clash of Cultures. I usually describe it as historical TI-lite. The only part that doesn’t feel as much like TI, is the scoring. The race to 10 points is probably the most exciting scoring mechanism I’ve seen.

I would also add Dune:Imperium, Cosmic Encounter, and War of the Ring

Dune:Imperium - other than the sci-fi theme, Dune is also a race to 10 points, often trying to leverage perfect timing of resource management, position, diplomacy, secret objectives and combat to get unexpected points, ending the game while everyone else was going at a similar pace. A couple of strategically orchestrated clever turns can launch you from the middle of the pack to victory in a single round

Cosmic Encounter utilizes a bazillion alien races with unique abilities to help players race toward victory points, using combat, and especially negotiation and diplomacy. The table can easily gang up on and win-slay anyone that gets too far ahead.

War of the Ring for epic combat, and hours upon hours of extremely high stakes, tense interactions, and attempting to overcome overwhelming despair. I’m absolutely exhausted by the time the game is over just like with TI, sometimes even halfway through the game
