Pretty much all games, even online MMO, live service and other games already have the capability to spin up a custom server or run solo and offline. How do you think the developers run the game while coding and testing? They just spin up a container on their machine. The added cost of polishing that or wrapping an installer around it should not be high.
I’m about to start the last act of Hardspace: Shipbreaker. It’s a fun relaxing sim game. If you enjoy games like “Powerwash Simulator” you’ll enjoy it. The setting is great, I hope it will expand into other games as well.
Don’t make dying harder than it has to. I really hate the mechanic in Hollow Knight where you had to go back to the place you died and battle your shade. It’s extremely punishing and unfun (for me). Compare that with Ori where, when you die, there is no extra penalty and the reload is almost instant, so you immediately get to go again. It keeps me in the flow.
For that same reason, bosses should only have a grand entrance, cut scene, etc once. When I die and go again I want to immediately fight him, I don’t want to have to sit through the same scene 30 times just because I suck. Not even if it’s just 5 seconds long. So, second time make sure the boss is spawned and waiting.
For me it wasn’t so much the runback, as it was fighting your spirit every time. I hated that. Especially if you died in a difficult platforming section. It only made it more difficult.
