The first photo showing the portal attracted me the most.
Welcome back. It's great to see you sharing your thoughts on gaming once again. A moment ago, I didn't know about Portal but your post provides a good overview of it and now its totally different.
Thank you for sharing your gaming experiences, and I look forward to reading more of your posts in the future.
