I have a theory, which is that video games ultimately exist to create the most complex simulation of defending Earth against alien threats possible, so that in the event aliens really do invade Earth, there will be people who know exactly how to respond. Is this theory plausible? Unlikely. Have I just made it up right now? Maybe. Is it a fun way to introduce the most complex variant of such simulations yet created? Hopefully!
Terra Invicta, if you're not already aware, is a blend of X-COM and grand strategy games like Crusader Kings 3. Developed by the creators of X-COM: The Long War, Terra Invicta asks "What if that war was even longer?". It's a dazzlingly complex geopolitical simulation that starts with real world conditions, demanding that you prepare Earth for alien invasion while contending with the full force of regular Earth politics. To succeed, you need to sufficiently align Earth with your chosen goal before the aliens arrive in force, whether that's resisting the Xenos, exterminating them, submitting to them, or escaping them by evacuating Earth.
