Planescape is a top-down RPG where you play as a strange immortal amnesiac who finds himself in a nexus of worlds based off of the Great Wheel in Dungeons and Dragons. You will be interact with a variety of strange dimensional travelers and spirits to find out your past and save reality from a maniacal deity. It is truly a classic, but perhaps not quite as perfect as many will say as it does carry a distinct flaw.
The games writing and world absolutely deserve the praise given, the land of Sigil and all within are fantastically made and the story is engaging from start to finish.
Planescape’s focus on writing though is not just it’s biggest strength, but it’s biggest weakness. As an actual RPG, Planescape is really just okay at best. Most of the quests are bog standard fetch quests and combat is awkward, nothing truly bad but nothing special and if it didn’t have such an interesting world Planescape would become boring quickly. This is a game you play to experience the world and writing, similar with games like Undertale, Myst, and Deadly Premonition. Go into it with the mindset of reading a book and you will probably love Planescape, go into it wanting to actually play an RPG and you will probably be disappointed.
