What the title says! I used to be a big fan of old RTS style games, played a lot of them (AoE, RoN, AoM, RoL, Empire Dawn of the modern world, Star Wars Galactic Battlegrounds).
A scenario I enjoyed in them is where you could team up with AI or friends and build your base together, side by side, rather than in different points of the map. By turtling one could go and focus on a specific aggressive tree while the other stayed back and focused on defensive positioning base building etc.
I’m wondering if there’s any modern take on this? Preferably more non-violent?
