That’s really interesting!
I just discovered a theory about the cause of the ‘late heavy bombardment’, which is thought to have delivered water to earth via comets.
Essentially the gas giants all orbited much closer, but Jupiter and Saturn got into resonance and flung Uranus and Neptune way out (and Saturn too). Uranus and Neptune flew out into the path of a heap of ice, and their gravity pulled the ice into an orbit that collided with the terrestrial planets.
Do you mean the Trojans? They’re excluded from the mass calculation of ‘clearing the neighbourhood’ because they’re in a resonant orbit - their orbit is a consequence of Jupiter’s mass.
Absolute size isn’t really in the criteria for a planet though. Pluto isn’t a planet because it shares its orbit with lots of other icy bodies in the Kuiper belt.
Titanfall 2 is an amazing game. It’s single player is one of the best - it never gets stale as there’s always a new mechanic, both as a ‘pilot’ (soldier) or in a titan, to master or a twist you didn’t see coming. The story itself is top notch, and it’s length is good.
If I remember right, you can pause at anytime, even in cutscenes. They’re not long though.
Plus, the multiplayer has been fixed just recently so you can vs others in some of the best feeling combat any game has to offer.
I’ve never played the others though, so feel free to go with them.
