Surviving Mars is really a colony sim, not a city builder. I've been playing it the last couple days, starts out really slow if you go with a normal start. The YT vid I watched was dated but it said to avoid any of the easy starting sponsors because it wouldn't really give you a good feel for the game.
I'm an old ass gamer, if it quacks and walks like a duck, I call it a duck. It plays like a city sim, with disasters maxed out at higher difficulties to me. What makes it unique for me, is the drone system that reminds me of C&C. Rather than defend/attack/harvest, it's harvest/repair/logistics. Shit is really fun to micro manage for me, I can't explain it, with all the various research upgrades, they get better and better too. AI is far from perfect, drones will often huddle in a group doing fuck all, while there is shit to be done right next to them.
I've messed around with a few games with difficulty high/maxed out, it completely changes the game into more of a hardscrabble survival strategy game. It's not just sponsors, game rules and map choice can lead to some brutal prison rape games as soon as you land. Did one game maxed out, wasn't going to last long anyway, then some event happened with my power, chose an option, and all my batteries fucking overloaded, since my wind/solar were right next to them, completely wiped out my power grid. Checkmate, no matter what I did, but now I space out
everything. Other games I've had events with power cables constantly needing repairs, so I had to add backups, rather than relying on a single utility line.
Happy medium for me is right in middle, enough random things to keep it interesting, and eventually you can completely negate all the environmental hazards.
Dealing with whiny bitch colonists is the true challenge. Every game I know I'm going to fail, I put switches/valves on the power/lifesupport for each dome, and then turn them off.
