Some of the PC games with the largest file sizes it can be a downright pain for gamers trying their best to make room for these titles on their discs. As long as players are sure to enjoy playing the titles of their choice, there's no denying that these games are worth installing, even if the space they take up can be downright overwhelming at times.

Forspoken
121.73 GB
Square Enix infamously handled their Western IPs appallingly and Forspoken is likely the last game financed by this publisher after the sale of developer Embracer Group. This attempt at an open-world isekai title was marred by many issues stemming from its gameplay and writing, resulting in a hot mess of a title that ended up underperforming in every way.
This game's traversal system may be a blast, but it's just not enough to justify players having to go through tedious story sequences and boring fights over and over again. Perhaps the biggest and most glaring flaw of this game is the fact that it takes up a whopping 150 GB of space, which is simply ridiculous and shows how poorly optimized this game is, with the demands of this game not justifying the bland and uninteresting visuals.

The latest chapter in Horizon the series may not have been able to capture the sense of awe and wonder that its predecessor absolutely did, but that shouldn't take anything away from this excellent game, which offers the same dense open world and combat that fans have come to love.
