Marvel's Midnight Suns should not have been for everybody. As a turn-based strategy game made by one of the best in the business, Firaxis Games' latest project you might have expected Marvel's Midnight Suns to simply excel in its own niche. After all, not everyone is a fan of tactical games. But, after reading through all the reviews, it appears Firaxis found a way to make the game appeal enough to both the casual gaming audience as well as the handful who are out for a more hardcore tactical gameplay experience.
Perhaps the best part about Marvel's Midnight Suns is that it combines three completely foreign concepts and merges them with each other. Naturally, one of its pillars is XCOM's combat system. But, at the same time, it also borrows a card-battle system similar to the ones found in Inscryption and Slay the Spire. To top everything off, Marvel's Midnight Suns has an expansive cast of an all-time Marvel crew, a new character, and an original storyline. But, while most would've had a hard time blending these elements, Firaxis found a way to give each one a chance to shine.
This probably explains why IGN said in its review that, "With Marvel's Midnight Suns, Firaxis has put itself in the league of RPG developers like BioWare, Obsidian, Bethesda, and Larian."
