I have played Portal! Unfortunately, my ability to rotate 3D shapes in my head is ABYSMAL (yes, I know, artist with terrible spatial intelligence, go figure) so I was really bad at it! I like Loved a lot, and I REALLY enjoyed Thomas Was Alone though. That pretty much fulfilled ALL my flea-jumping fantasies, PLUS pushed my happy robot story buttons too.

It's why I like watching people play horror games, honestly; those games tend to have more running and screaming than fighting.
