I've never heard of this series but by these comments it seems I'm missing out. Is this a puzzle game similar to Cube for Psone? If so, I'll pass.

No, it's closer to HL2 then to D-Cube. If you haven't played this, especially when you own it, you really missed something. Portal has a great story, has great gameplay, and involves some inuitive thinking. It's best described as a first-person puzzle platformer imo.
