Fallout 4 - Absolutely loved this game a couple of years ago, turned sanctuary into a fortress. Had to stop playing in the end as the settlement was too big and it kept glitching. I don't think there was a set of Power Armour I didn't own.
Fallout 4 was the reason why I upgraded every part of my PC apart from the sound card and the drives. I have it modded for construction. Height limit removed, thousands of extra building items and, most importantly of all, the Place Everywhere mod. Absolute game-changer, that mod. All in all, I had dozens of building-related mods installed. I spent many hours scavving because I decided that I would acquire everything I needed for the building ingame. No free building, no resource-increasing mods, no console commands to summon resources. Also, no framerate It dropped under 10 fps in the settlement I was working on at the time. I think 4fps was the lowest I saw. Somewhere around that. That wasn't even Sanctuary, which would have been the biggest settlement. I turned that into a walled city, but it was the first settlement I worked on and it wasn't very complex. It was Starlight that prompted the upgrade. I'd turned it into a trading hub city, with a theatre, a library, a hospital, a tavern, an inn, a rooftop restaurant (called, unsurprisingly, Starlight), a laundrette (fully functional - one mod I installed created working washing machines) and, the main framerate tank, a block of flats. 36 sizeable flats, each one fully furnished and individually decorated. Do It Yourshelf and Creative Clutter mods are the dog's danglies for decorating Fallout 4 settlements.
I never did finish Starlight. I kept switching between my settlements (~30, IIRC) roleplaying as a benevolent but slightly unhinged dictator. So I'd improve the living standards for all my
The last game I completed was Dead State Reanimated, which I'd give a solid 8/10. Looks very dated. Badly optimised. Buggy enough to have CTDs. Combat is very slow if there are more than a few enemies in the area as the game slowly churns through a turn for every one of them, including seconds of animation for enemies not even within view. But a very good game nonetheless.
