Recommendation:
I absolutely recommend this game to anyone who likes completing story-driven games in 1 session. It has interesting puzzles, and some good literature.

Story (no spoilers):
I cant speak on behalf of the story in relation to the whole series, but as a standalone game the story can be interpreted in its own unique way. My friends and I came up with a pretty good one. If this is your first time playing a game in this series, I encourage you to give the story some thought once you've achieved all endings!

Length:
The Room 3's base game took me and 2 other friends that were watching a little over 4 hours to complete. Another hour was needed to 100% the game's achievements.

Bugs:
Most complaints about bugs in this game's discussions are just from people that haven't solved the puzzles correctly.
We ran into 0 bugs while playing the base game and only 1 soft-lock (arguably my fault for going too quickly) while going for 100%. This honestly wasn't even a huge issue, as regaining the lost progress took less than 5 minutes.
