Verticality in Solasta mean flying, levitation, walking on the walls, push creatures, take cover, break the lign of sight to re-hide etc etc... Everything that allow you to play with verticality in D&D.
There are many new things no TB games had done before if I'm not wrong.
In BG3 it's currently limited to push ennemies and going "higher" (walking, jumping, basic actions) to increase your %to hit.
At the moment I understand why it was a selling point in Solasta because it add something new. I don't really in BG3 but I hope they have more things in mind than "shove" and the very common in TB games "our position really matter".
Pretty much. Solasta has it implemented a lot more thoughtfully than 'get to high ground or else you're going to have a really bad time'. Verticality is an optional but tactical feature there, not a mandatory system that you're forced to interact with in every fight.
Certain enemies love to abuse flight and wall-walking against you in Solasta, but it's balanced out by the fact that you can easily do the same thing yourself with certain equipment and spells, ready actions exist so that you can just wait for them to come to you as most of those enemies only have melee attacks, and that fall damage is a lot more lethal there if you manage to knock them down (via a sleep spell, shoving a wall-hugging enemy off that wall, or breaking their concentration if their flying or wall-walking is spell-based instead of an inherent ability).
