I thought HS2 was a keeper until I understood my tastes better and how restricting limited pin space would eventually become, so I sold it.
My current keepers are games I can't replace in their current condition without spending additional months of my life. I have thousands of dollars and months of restoration in my TZ. I spent 2 years searching for TX-Sector. I only have so long to live, so I don't want to go through that again.
