Well, any RTwP game, if you take into account the "imagine playing with friends, everyone constantly pausing, what a nightmare".
No, I don't take that into account. Like at all.
There's a hundred games out there already that I can play if I want MP.
And if by any remote chance Larian are sacrificing core BG elements and gameplay dynamics in order to make a multi-player first, co-op, cross-play, mobile friendly mess... Heh... I hope they like losing money.
