That must be either Costume Quest II or South Park: The Fractured but Whole

Costume Quest 2 is correct!

It's been ages since I played that game, one of the first I bought digitally. I wasn't sure anymore if the fights were turn-based or not.

#45: Super Mario Bros. 3

• The game that introduced the main villain's children into the series, though in later games this has been retconned and these days they are just the villain's minions.

#44: The Legend of Zelda: Breath of the Wild

• Some really brittle weapons in this one

#43:

• The Core and the Arm
• A four-thousand-year conflict between the two sides
• A sci-fi RTS with a sequel that went with a fantasy setting
• Said sequel had the subtitle Kingdoms

#42: A Plague Tale: Requiem

• Even more rats
• She really just can't catch a break

#41: Theatrhythm Final Bar Line

• A rhythm game built around the music of one of the few video game series that could support an entire game with just its music
• This was the first home console entry in the spin-off series, having had two handheld titles and an arcade release before this one, as well as another game based on a different series of RPGs

Total Annihilation?

#43 - A base-building game where your handful of people must survive the end of the world, as hell has taken over.

1. First you just need to survive, but after a while your group of survivors will do things like farming, crafting, both scientific and occult research, build shrines for rituals and an alchemic table complete with a philosopher's stone.
2. Research needs sometimes some specific items that you can scavenge, as in scientific books, research kits, scientific data to progress in that tech tree.
3. The more survivors you rescued and the more buildings you constructed, the more the forces of hell are aware of you and will attack your base more often.
4. Each survivor belongs to a class, but they will also have some additional talents that can influence a survivor in different ways.

#42 - A very long turn-based Fantasy game with clear influences at Civilization, Master of Magic and Heroes of Might & Magic.

1. The game world consists of a planet that has been blown to bits to avoid the forces of chaos to take it over, and the main story consists of assembling those shards and combining them with yours to recreate the planet.
2. This game has been made twice, once in 2D and then immediately they recreated it in 3D, although to this day with piss-poor performance.
3. Battles are turn-based in a manner similar to Heroes of Might & Magic, but every unit is singular instead of a group of troops and the hero is actively fighting along with them. Also, how many units one can bring along depends on the hero's command skill, and how high this can go depends on his class.

#40 - A Pinball game with 3 tables that would be pretty much impossible to make in reality

1. It has a halloween/dark fantasy setting

#39 - Stealth, Sniping or big guns, whatever approach floats your boat in this game is possible.

#38 - Thwart an Alien Invasion with a team of soldiers and some researchers trying to reverse-engineer the alien tech into something useable by humans. 

#45 - Rudra no Hihou (SNES)

A RPG made by Square back in the SNES days really couldn't go wrong. And of course, Rudra no Hihou is no exception. With 4 campaigns, a lot of spells to master, and a wonderful combination of great graphics and soundtrack, this is still one of my favorite RPGs. Too bad it never leaved Japan, because it had the potential to be a memorable game for many more people around the world.

Correct.

#47 Tyrian

Being one of the few shooters I like Tyrian also was the only non-education game that for some reason was installed on the school computer. With a cool generator system and a lot of very different weapons as well as being able to buy and sell at will between levels Tyrian became my benchmark for any scrolling shooter going forward. Collecting money on the level and spend it to upgrade the cheapest weapon to the max just to see how it looked is something I miss in pretty much each other shooter I try. 

Secrets like the carrot ship, hot-dog weapon and hidden levels mad it fun for revisits. And the harder difficulty levels are brutal and demands not only how to avoid enemy fire but where to focus own fire in order to get any kills. Even the story (for at least the first 4 episodes) is a cool sci-fi drama with a touch of humor and humanity rarely seen in other games of the genre.   

#46 Theme Hospital

I have yet to beat this game. The version I played on always bugged out on the later levels. But I played it a lot. Before The Sims this game made it possible to build rooms and place furniture. Probably the first game I played that had voice acting in my native language. 

This game screams funny in every corner. From the unique strange illnesses of the patients to the secretary asking them to not die in the corridors.  Janitors with questionable smells, rats that can be shot, emergencies with groups of people that think they are Elvis and need to see a psychologist. And who could forget the intro cinematic where the doctor did not succeed in stabilizing the patient using a chainsaw to operate and therefore presses the eject button dropping the patient down a dark empty hole. Cannot let them leave a bad review.
