Square Circle has many of the best parts of an Eric Eve game. Great NPCs and conversation, an expansive map that doesn't need too much mapping, a large number of items, and smooth writing.
The plot wasn't as compelling as other Eric Eve games, but it was still pretty good. You are put in prison, your memory erased, until you can make a 'square circle'.
The solution to this puzzle was unexpected to me, and I used a hint, but it was fun. What was much more fun, however, was the psychological drama that unfolded for the rest of the game.
This game was well-regarded for its puzzles, and I found them fun as well. I prefer Nightfall, Blighted Isle, and All Hope Abandone by Eve to this game, but it is still a very good game.
Recommended for everyone.
